Sparse matrix class emulating the CSR matrix format by internaly storing A.'.
This class can singificantly improve the performance of your application when the code is dominated by matrix-vector multiplcations.
Usage: Create a sparseCSR matrix using the syntax
A = sparseCSR();
A = sparseCSR(B);
A = sparseCSR(N, M);
A = sparseCSR(I, J, V);
A = sparseCSR(I, J, V, N, M);
where B can be either a full or a sparse matrix, N, M are the number of rows and columns, and I, J, and V are the row, column, and value vectors of A.
Convert a sparseCSR matrix using sparse(A) or full(A) into a sparse or dense matrix.
Several functions are overloaded aiming to naively use a sparseCSR matrix instead of a sparse matrix.
