Function cusparseCreateDnMat 

pub unsafe extern "C" fn cusparseCreateDnMat(
    dnMatDescr: *mut cusparseDnMatDescr_t,
    rows: i64,
    cols: i64,
    ld: i64,
    values: *mut c_void,
    valueType: cudaDataType,
    order: cusparseOrder_t,
) -> cusparseStatus_t

The function initializes the dense matrix descriptor dnMatDescr.

cusparseCreateDnMat has the following constraints:

• values must be aligned to the size of the datatype specified by valueType. See cudaDataType_t for the description of the datatypes.

Parameters

• dnMatDescr: Dense matrix descriptor.
• rows: Number of rows of the dense matrix.
• cols: Number of columns of the dense matrix.
• ld: Leading dimension of the dense matrix.
• values: Values of the dense matrix. Array with size elements.
• valueType: Enumerator specifying the datatype of values.
• order: Enumerator specifying the memory layout of the dense matrix.
