Currently: p [r_] := Piecewise [ { {2/ (\ [Epsilon]0*r) + (3 r^2)/\ [Epsilon]0, 0 <= r <= 1}, {4 r/\ [Epsilon]0, 1 <= r <= 2}, {16/ (\ [Epsilon]0*r), r >= 2}}] Plot [p [r] /. \ [Epsilon]0 -> 1, {r, 0, 4}, ExclusionsStyle -> { {Red, Dashed}, Blue}] So, using p [r] /. \ [Epsilon]0 -> 1nlm = NonlinearModelFit[v40s1000h,Piecewise[{{a, x < A}, {b, x > B}}], {a, b, A, B, c, d}, x] This creates a decent fit only if I specify the values for A and B, but then I have to estimate those values for each data set manually. It also doesn't really work to just add NMinimize, or add the piecewise part for the middle bit.I want to specify a piecewise function by writing f[x_]:=Piecewise[piecewiseComponents], and use a loop to specify the components.

Wolfram Universal Deployment SystemIntegrate can evaluate integrals of rational functions. It can also evaluate integrals that involve exponential, logarithmic, trigonometric, and inverse trigonometric functions, so long as the result comes out in terms of the same set of functions. Integrate can give results in terms of many special functions.

The following worked in some previous version of Mathematica (but same problem as I see above with copy-and-paste). StreamPlot[{1, Piecewise[{{0.4 p (1 - p/30), 0 < t <= 5}, {0.4 p (1 - p/30) - 0.25 p, t >= 5}}]}, {t, 0, 10}, {p, …Neat Examples (2) LaplaceTransform [f [t], t, s] gives the symbolic Laplace transform of f [t] in the variable t and returns a transform F [s] in the variable s. LaplaceTransform [f [t], t, OverscriptBox [s, ^]] gives the numeric Laplace transform at the numerical value OverscriptBox [s, ^].

Piecewise Piecewise. Piecewise. Piecewise [ { { val1, cond1 }, { val2, cond2 }, …. }] represents a piecewise function with values val i in the regions defined by the conditions cond i. Piecewise [ { { val1, cond1 }, … }, val] uses default value val if none of the cond i apply. The default for val is 0.Such function are not "differentiable everywhere" because the limit techniques which underlie derivative methodology do not work on hard corners. Using Mathematica, it is easy to plot a piecewise discontinuous function. An example of a Piecewise function is given below. There are three different functions that have been generated in a single graph.Compute the Fourier series of piecewise functions. Get the free "Fourier Series of Piecewise Functions" widget for your website, blog, Wordpress, Blogger, or iGoogle. Find more Mathematics widgets in Wolfram|Alpha.They are also at the core of many computational methods, including splines and finite elements. Special cases include such functions as RealAbs, UnitStep, Clip, RealSign, Floor, and Max. The Wolfram Language handles piecewise functions in both symbolic and numerical situations. This generates a square wave:

$\begingroup$ Ok, so in general I can extract each region of a piecewise function, solve for the region (assuming the integration is possible), impose the continuity conditions as you did, and then stick each piece back together. I can attempt to write a code for that.

Something different occurs when you use Piecewise. This Piecewise command is developed to be evaluated in expressions such as as Integrate, Minimize, Reduce, DSolve, and Simplify, as well as their numeric analogs. So, when you used inside this last set of functions what occurs is something like this. Piecewise[{conditions in terms of t}] /.

The rectangle function Pi (x) is a function that is 0 outside the interval [-1/2,1/2] and unity inside it. It is also called the gate function, pulse function, or window function, and is defined by Pi (x)= {0 for |x|>1/2; 1/2 for |x|=1/2; 1 for |x|<1/2.

Your functions can be combined into one well defined piecewise function, In the following {0,True) assigns the value zero to the function outside the defined intervals: pw [x_] := Piecewise [ { {2 x - 3 , -4 <= x <= 1}, {-7 x + 2 , 1 < x <= 5}, {0,True}}] You can plot this (as desired). I have used ExclusionStyle to show ... Nasser's solution is suitable for teaching canonical use of Piecewise. It defines a base function and then defines a periodic function based on it, perhaps using T as a parameter. Ted Ersek's solution shows the Gibb's phenomenon that alludes to MMa's use of Series being used in the background. My thanks to all the respondents. $\endgroup$

I am trying to plot using piecewise in one of my problems and I have two variables: x and psi. However, the respective functions are only valid for a defined range of "x" and the psi range is the same. I am trying to make a 3D plot of these -- and I basically just have Plot3D [p, {x,0,1}, {psi ...Application of Definite integrals of piecewise function.

Wolfram Universal Deployment System$\begingroup$ Hi TimSch -- it would help if you could put your equations into Mathematica code and show exactly what you tried when taking the Fourier coefficients. Sometimes the problem can be with syntax, and sometimes with particular assumptions that need to be made -- for instance, you haven't specified what $\hat{u}$ is, is it real-valued, and does Mathematica know to make this assumption ...

Mathematical function, suitable for both symbolic and numerical manipulation. For nonzero complex numbers z, Sign [z] is defined as z /Abs [z]. Sign tries various transformations in trying to determine the sign of symbolic expressions. For exact numeric quantities, Sign internally uses numerical approximations to establish its result. Nasser's solution is suitable for teaching canonical use of Piecewise. It defines a base function and then defines a periodic function based on it, perhaps using T as a parameter. Ted Ersek's solution shows the Gibb's phenomenon that alludes to MMa's use of Series being used in the background. My thanks to all the respondents. $\endgroup$Another way is as follows. f = Function [x, Piecewise [ { {-1, x > 1}, {0, x <= 0}, {1/Floor [1/x], x > 0 && x <= 1}}]] Well, I explicitly said that Im not interested in this answer. And the expression you put here is not equivalent to the definition of the original function. You must use a ceil function of the kind. not a floor one.Mathematica Stack Exchange is a question and answer site for users of Wolfram Mathematica. It only takes a minute to sign up. ... I'm trying to maximize piecewise functions with parameters but haven't been able to do so. Here is a minimum example: f[x_, a_] = -(x - 10*a)^2 + 50*a; w[x_, a_] = \[Piecewise] { {f[x, a], 1/2 < a < 8/x && 0 < x < 20 ...Piecewise construct for representing general piecewise functions.

As I mentioned in a comment, NIntegrate does solve the condition 1.1 x^0.045 < 1 for the singularity at x == b2bar and this causes a problem with the integration, which is itself an issue. But that issue can be avoided by reducing the condition to something NIntegrate can handle. If we throw in the domain restriction 0 <= x <= 1 && 0 <= y <= 1 …Neat Examples (2) LaplaceTransform [f [t], t, s] gives the symbolic Laplace transform of f [t] in the variable t and returns a transform F [s] in the variable s.

Piecewise [ { { val1, cond1 }, { val2, cond2 }, …. }] represents a piecewise function with values val i in the regions defined by the conditions cond i. Piecewise [ { { val1, cond1 }, … }, val] uses default value val if none of the cond i apply. The default for val is 0.Dec 17, 2015 · If none of the conditions above it evaluate to True, then the last condition automatically evaluates to True, and the function spits out a 0. You can change that default by explicitly putting in, say {-1, True}. Piecewise tests its arguments in order: for example, ponder on the output when you evaluate Piecewise[{{-1, True}, {1, x > 0 ...

So the only possibility to get an explicit interpolating function is to re-implement the built-in Interpolation in the high-level Mathematica language. kitchenaid dishwasher clean light flashing 7 times Feb 25, 2014 · and you want to create a Piecewise function creator. First, you need to think about how to construct each of the linear functions. E.g. from x=1 to x=2 we need a linear function going from 5 down to 1. From x=2 to x=3 we need a function going from 1 up to 3 and so on. This is simple math, but you can also use Mathematica for this: A person with high functioning bipolar disorder has learned to mask their symptoms but not manage them.
