"WebApr 20, 2024 · BSR is format storage sparse matrix, mainly used in intel MKL solver. Uniform blocks are spilted in original matrix and the zero-blocks and non-zero-blocks are exactly in the blocks. NOTED THAT, the dimension of original matrix must be the integer multiple of the block dimension, ensuring the matrix can be spilt uniformly. " - Bsr matrix format
