Function 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 B^{-1}A.

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 The index of the column to compute. @param col_vector An array of length [num_row] in which to store the values of the non-zero elements. @param col_num_nz The number of non-zeros in the column. @param col_index An array of length [num_row] in which to store the indices of the non-zero elements.

@returns A kHighsStatus constant indicating whether the call succeeded.
