Function compress_jacobian_pattern 

pub fn compress_jacobian_pattern(
    sparsity: &CsrArray<f64>,
) -> Result<CompressedJacobianPattern, OptimizeError>

Compresses a sparse Jacobian pattern for more efficient finite differencing

Uses a simplified Curtis-Powell-Reid algorithm with graph coloring to group columns that can be computed simultaneously without interference.

Arguments

• sparsity - Sparse matrix representing the Jacobian sparsity pattern

Returns

• Compressed sparsity pattern and compression matrices (original, B, C) where B is the column compression matrix and C is the row compression matrix
