Function xgetrs 

pub fn xgetrs<TA: DataTypeLike, TB: DataTypeLike>(
    ctx: &Context,
    params: &Params,
    operation: Operation,
    n: usize,
    nrhs: usize,
    a: MatrixRef<'_, TA>,
    pivots: &DeviceMemory<i64>,
    b: MatrixMut<'_, TB>,
    dev_info: &mut DeviceMemory<i32>,
) -> Result<()>

Solves a linear system of multiple right-hand sides

where A is an $n \times n$ matrix, and was LU-factored by xgetrf, that is, lower triangular part of A is L, and upper triangular part (including diagonal elements) of A is U. B is an $n \times {nrhs}$ right-hand side matrix.

The operation argument is described by Operation.

pivots is an output of xgetrf. It contains the pivot indices used to permute the right-hand sides.

If the reported info value is -i, the ith parameter is invalid.

Callers can combine xgetrf and xgetrs to complete a linear solver.

Currently, xgetrs supports only the default algorithm.

List of input arguments for xgetrs:

The generic cuSOLVER routine has two data types: data_type_a is the data type of matrix A, and data_type_b is the data type of matrix B. xgetrs only supports the following four combinations:

Valid combination of data type and compute type

data_type_a	data_type_b	Meaning
DataType::F32	DataType::F32	SGETRS
DataType::F64	DataType::F64	DGETRS
DataType::ComplexF32	DataType::ComplexF32	CGETRS
DataType::ComplexF64	DataType::ComplexF64	ZGETRS

Errors

Returns an error if cuSOLVER has not been initialized, if the matrix dimensions or leading dimensions are invalid, or if cuSOLVER reports an internal failure.
