Function triangular_solve_matrix_in 

pub fn triangular_solve_matrix_in<T>(
    session: &mut dyn Engine,
    a: &Matrix<T>,
    b: &Matrix<T>,
    left_side: bool,
    lower: bool,

Solve a triangular system on a caller-held engine.

Same kernel, conversion and validation as triangular_solve_matrix, entered through the given engine instead of the process-global context.

Errors

Returns BackendLinalgError under the same conditions as triangular_solve_matrix.
