Function highs_sys::Highs_getReducedColumn

pub unsafe extern "C" fn Highs_getReducedColumn(
    highs: *const c_void, 
    col: HighsInt, 
    col_vector: *mut f64, 
    col_num_nz: *mut HighsInt, 
    col_index: *mut HighsInt
) -> HighsInt

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

See Highs_getBasicVariables for a description of the B matrix.

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

@param highs a pointer to the Highs instance @param col index of the column to compute @param col_vector values of the non-zero elements @param col_num_nz the number of non-zeros in the column @param col_index indices of the non-zero elements

@returns a kHighsStatus constant indicating whether the call succeeded
