Is it possible to reverse the following in matlab:
[U,S,V]=svds(fulldata,columns);
Quoting MathWorks:
[U,S,V] = svd(X) produces a diagonal matrix S of the same dimension as X, with nonnegative diagonal elements in decreasing order, and unitary matrices U and V so that X = U*S*V’.
In the case of svds, one will lose some information unless
columnsis equal to the size of the square matrixfulldata. In this case, I believe the original matrix cannot be reconstructed uniquely.
