spget

retrieves entries of sparse matrix

Syntax

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

Arguments

sp

real, complex or boolean sparse matrix

ij

two columns integer matrix (indices of non-zeros or true 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 (or entries set to true for a boolean sparse matrix) 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);
