Synopsis
`coef = problem.getCoef(row, col)`
Arguments

row: constraint | Row of the constraint matrix.
col: var | Column of the constraint matrix.

Return value

coef: float | The coefficient.

Further information
1. It is quite inefficient to get several coefficients with the problem.getCoef function. It is better to use problem.getCols or problem.getRows.
2. Argument row may contain either xpress.constraint objects or integer indices.
3. Argument col may contain either xpress.var objects or integer indices.
