Get all row elements from the matrix.

int get_row(lprec *lp, int rownr, REAL *row);

Return Value

get_row returns TRUE (1) if the operation was successful. A return value of FALSE (0) indicates an error.
An error occurs when rownr is not between 0 and the number of rows in the lp.



Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_lp_file, read_LP, read_mps, read_MPS


Row number of the matrix. Must be between 0 and number of rows in the lp. Row 0 is objective function.


Array in which the values are returned. The array must be dimensioned with at least 1 plus number of columns elements in the lp.


This function retrieves all values for the given row.
Element 0 of the row array is not filled. Element 1 will contain the value for column 1, Element 2 the value for column 2, ...
