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);
