slu.matrix.createSparseCOO
Create a sparse matrix in Coordinate (COO) format.
Syntax
slu.matrix.createSparseCOO(m, n, rows, cols, values, dtype?)
Description
Create a sparse matrix in Coordinate (COO) format. COO format (also called triplet format) stores each nonzero as a (row, column, value) triplet. This format is convenient for constructing matrices incrementally but less efficient for arithmetic.
Parameters
| Name | Description |
|---|---|
| m | - Number of rows |
| n | - Number of columns |
| rows | - Row indices for each nonzero |
| cols | - Column indices for each nonzero |
| values | - Nonzero values |
| dtype(optional) | - Data type (default: 'float64') |
Returns
SparseMatrixCOO
