problem.getcoefformula

Purpose
Retrieve a single nonlinear matrix coefficient as a formula split into tokens
Synopsis
(factor, tokencount, type, value) = problem.getcoefformula(row, col, parsed, maxtypes)
Arguments
row 
The row index for the coefficient.
col 
The column index for the coefficient.
parsed 
Integer indicating whether the formula of the item is to be returned in internal unparsed format ( parsed=False) or parsed (reverse Polish) format ( parsed=True).
maxtypes 
Maximum number of tokens to return, i.e. length of the type and value arrays.
Return value
factor 
The value of the constant factor multiplying the formula in the coefficient.
tokencount 
Number of tokens returned in type and value.
type 
Array holding the token types for the formula.
value 
Array of values corresponding to type.
Example
The following example displays the formula for the coefficient in row 2, column 3 in unparsed form: 
(fac, tc, type, value) = p.getcoefformula(2, 3, 0, 10)
Further information

The type and value arrays are terminated by an xslp_op_eof token.

If the requested coefficient is constant, then factor will be set to 1.0 and the value will be returned with token type xslp_op_con.
