IJV

Returns I,J,V triplets from a sparse matrix.

Syntax

• [iv, jv, vv, m, n, nzmax] = IJV(sp)

Input argument

• sp - a sparse matrix.

Output argument

• iv - a vector: row indices of the nonzero elements.
• jv - a vector: column indices of the nonzero elements.
• vv - a vector: values of the nonzero elements.
• m - an integer value: number of rows in the matrix.
• n - an integer value: number of columns in the matrix.
• nzmax - an integer value: reserved size for nonzero elements..

Description

IJV converts a sparse matrix into its COO format.

Example

sp = sparse(eye(3,3))
[IV, JV, VV, m, n, nzmax] = IJV(sp)
