Topic areas
SLP, Problem Information, Nonlinear
Synopsis
factor, formula = problem.slpGetCoefStr(row, col)
Arguments
row: constraint 
Integer holding the row index for the coefficient.
col: var 
Integer holding the column index for the coefficient.
Return value
factor: float 
A double precision variable to receive the value of the constant factor multiplying the formula in the coefficient.
formula: str 
Character buffer containing the formula in the same format as used for input from a file.
Further information
1. If the requested coefficient is constant, then factor will be set to 1.0 and the value will be formatted in formula.
2. Argument row may contain either xpress.constraint objects or integer indices.
3. Argument col may contain either xpress.var objects or integer indices.
