Hi,
A = sparse ([1:10, 10], [1:10,5], [1:10 1], 10,10)
A =
Compressed Column Sparse (rows = 10, cols = 10, nnz = 11)
(1, 1) -> 1
(2, 2) -> 2
(3, 3) -> 3
(4, 4) -> 4
(5, 5) -> 5
(10, 5) -> 1
(6, 6) -> 6
(7, 7) -> 7
(8, 8) -> 8
(9, 9) -> 9
(10, 10) -> 10
octave:5> spinv (A)
error: division by zero
warning: spinverse: matrix singular to machine precision, rcond = 0
This does not make much sense?
Tested on Octave 2.9.9 and 2.9.7
Regards,
Gorazd
