csr_trans() def csr_trans ( m  , n  , val  , ptr  , ind  , base  , val2  , ptr2  , ind2  , base2    ) Transpose matrix (CSR) Purpose This routine computes the transpose of input matrix in CSR format. Returns info (int) = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. Parameters [in] m Number of rows of the matrix. (m >= 0) (if m = 0, returns without computation) [in] n Number of columns of the matrix. (n >= 0) (if n = 0, returns without computation) [in] val Numpy ndarray (1-dimensional, float, nnz) Values of nonzero elements of input matrix (nnz is the number of nonzero elements of input matrix). [in] ptr Numpy ndarray (1-dimensional, int32, n + 1 (if CSC) or m + 1 (if CSR)) Column pointers (if CSC) or row pointers (if CSR) of input matrix. [in] ind Numpy ndarray (1-dimensional, int32, nnz) Row indices (if CSC) or column indices (if CSR) of input matrix. [in] base Indexing of ptr and ind. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. [out] val2 Numpy ndarray (1-dimensional, float, nnz) Values of nonzero elements of output matrix (nnz is the number of nonzero elements of input matrix). [out] ptr2 Numpy ndarray (1-dimensional, int32, n + 1 (if CSC) or m + 1 (if CSR)) Column pointers (if CSC) or row pointers (if CSR) of output matrix. [out] ind2 Numpy ndarray (1-dimensional, int32, nnz) Row indices (if CSC) or column indices (if CSR) of output matrix. [in] base2 Indexing of ptr2 and ind2. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1.
