scripts default iconSPINIT (Scripts) Publisher's description

This utility can be useful when you need to update a sparse matrix values

This utility can be useful when you need to update a sparse matrix values
without changing its sparsity pattern.

Since MATLAB uses CSC (Compressed Sparse Column) format for sparse matries, the non-zeroes are stored in an array, which can be safely overwritten in order to update the matrix, while preserving the sparsity pattern.

This can be done much faster than re-allocating the whole sparse matrix again, when only its values change.

The source code can be found at GitHub:
