SPRSTP

The SPRSTP function constructs the transpose of a sparse matrix.

Examples

This example creates a 100 by 100 pseudo-random sparse matrix, with 1000 non-zero elements, and then computes the product of the matrix and its transpose:

n = 100                   ;Dimensions of matrix

m = 1000                  ;Number of non-zero elements

a = SPRSIN(RANDOMU(seed, m)*n, RANDOMU(seed, m)*n, $

    RANDOMU(seed, m),n)

b = SPRSAB(a, SPRSTP(a))  ;Transpose and create the product

Syntax

Result = SPRSTP(A)

Return Value

Returns the sparse matrix of the given sparse array.

Arguments

A

A row-indexed sparse array created by the SPRSIN function.
