How do I find the singular values of an array?

To get the singular values of an array you can do the following:

v = svds(SuaMatriz);

This function computes the six largest singular values of the matrix, as well as the associated vectors.

If you need more or less unique values you can use:

v = svds(SuaMatriz, NumeroDeValoresSingulares);
