spget Scilab Function

spget - retrieves entries of sparse matrix

Calling Sequence

[ij,v,mn]=spget(sp)

Parameters

sp : real or complex sparse matrix
ij : two columns integer matrix (indices of non-zeros entries)
mn : integer vector with two entries (row-dimension, column-dimension)
v : column vector

Description

spget is used to convert the internal representation of sparse matrices into the standard ij, v representation.

Non zero entries of sp are located in rows and columns with indices in ij.

Examples


sp=sparse([1,2;4,5;3,10],[1,2,3])
[ij,v,mn]=spget(sp);
