Function highs_sys::Highs_getReducedRow

pub unsafe extern "C" fn Highs_getReducedRow(
    highs: *const c_void, 
    row: HighsInt, 
    row_vector: *mut f64, 
    row_num_nz: *mut HighsInt, 
    row_index: *mut HighsInt
) -> HighsInt

Compute a row of \f$B^{-1}A\f$.

See Highs_getBasicVariables for a description of the B matrix.

The arrays row_vector and row_index must have an allocated length of [num_row]. However, check row_num_nz to see how many non-zero elements are actually stored.

@param highs a pointer to the Highs instance @param row index of the row to compute @param row_vector values of the non-zero elements @param row_num_nz the number of non-zeros in the row @param row_index indices of the non-zero elements

@returns a kHighsStatus constant indicating whether the call succeeded
