Hi,
I have two sparse matrices (say A and B).

I wish to implement the least squares operator : A\B
When I run this in MATLAB, I get
> size(A\B)
ans =
2440 2400
and A\B is a sparse matrix.
When I implement this in octave, I get
> A\B
ans = Compressed Column Sparse (rows = 0, cols =0, nnz = 0)
which is empty.
Is there a separate function in octave for this operation on
sparse matrices ?
Thanks,
Rishi
What version of Octave are you running?
I am running the latest stable version: 3.0.3
Thanks,
Rishi
Where did you get your version of Octave? Is it built with SuiteSparse? I don't see this issue with 3.0.3 on my machine
