The SVD comand gives me more the "S" matrix(31x31) , which contains the eigenvalues. Then I add colums of ceros, so i have a new S (31x57). Then I also have the A matrix by default. A(31x57)-U(31x31)*S(31x57)*V(57x57)= zero (31x57), I only have reliable data for A and S. And I will use one...

Thank you. Exactly, the full SVD like in the other software.

yes I have a matrix "A" of 31 rows and 57 columns. i have the size mismatch message. matrix V vector sing_val matrix U matrix U=@svd(A,sing_val,V) The type of descomposition I need is this one: A(mxn)= U(mxm)*S(mxn) *V(nxn), this is my main concern and the SVD for non-symetric gives u this...

I get the "mistmatch message" when using @svd to a non-symetric matrix of 37x51. Are u sure, the formula can run for non-symetric matrices?

I just found that Eviews only allows it to symetric matrices, because of complex numbers. Anyone have a suggestion on how to do it in eviews. I don't really know if it's possible doing it manually. Need something like the "fullsvd" function of stata, though I don't use that software.
