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);
