![]() ![]() If X is a multidimensional array, then find returns a column vector of the linear indices of the result. If X is a vector, then find returns a vector with the same orientation as X. e eig (A,B) returns a column vector containing the generalized eigenvalues of square matrices A and B. In linear algebra, the singular value decomposition ( SVD) is a factorization of a real or complex matrix into a rotation, followed by a rescaling followed by another rotation. k find (X) returns a vector containing the linear indices of each nonzero element in array X.

Matlab allows the users to find eigenvalues and eigenvectors of matrix using eig () method. ![]() It can create vectors, subscript arrays, and specify for iterations. Creating a matrix is as easy as making a vector, using semicolons ( ) to separate the rows of a matrix. The colon is one of the most useful operators in MATLAB ®. The complexity is O(n + k.log(k)), where n is the size of the array, and k is the number of elements to be. One area in which MATLAB excels is matrix computation. It is done by Bruno Luong using a partial quick-sort algorithm implemented with C-MEX. ![]() I found a good mex implementation there while searching for the same thing. Left: The action of V ⁎, a rotation, on D, e 1, and e 2. You can find good answers to matlab questions also on matlabcentral.Top: The action of M, indicated by its effect on the unit disc D and the two canonical unit vectors e 1 and e 2. ![]()
