Elements Equal to Specific Values. To find a specific integer value, use the == operator. For instance, find the element equal to 13 in a 1-by-10 vector of odd integers. x = 1:2:20. x = 1×10 1 3 5 7 9 11 13 15 17 19. k = find (x==13) k = 7. To find a noninteger value, use a tolerance value based on your data. The eigenvectors in V are normalized so that the 2-norm of each is 1. If A is symmetric, then the eigenvectors, V, are orthonormal. [V,D] = eigs (A,B) returns V as a matrix whose columns are the generalized right eigenvectors that satisfy A*V = B*V*D. The 2-norm of each eigenvector is not necessarily 1. To find the amplitudes of the three frequency peaks, convert the fft spectrum in Y to the single-sided amplitude spectrum. Because the fft function includes a scaling factor L between the original and the transformed signals, rescale Y by dividing by L.Take the complex magnitude of the fft spectrum. The two-sided amplitude spectrum P2, where the …squareform returns a symmetric matrix where Z (i,j) corresponds to the pairwise distance between observations i and j.
