_______________________________________________________
Details:
The following shows that there is a problem with the sparse matrix
pseudoinverse.
octave>> A = [2 ; 1]; B = [2 -1 0 ; 3 0 1];
octave>> A \ B
ans =
1.400 -0.400 0.200
octave>> sparse(A) \ sparse(B)
ans = Compressed Column Sparse (rows = 0, cols = 0, nnz = 0)
octave>> sparse(A) \ B
ans = [](0x0)
I am using 3.6.3 with no extra sparse matrix libraries (AMD,...).
