problem.getcoefformula

Purpose

Retrieve a single matrix coefficient as a formula split into tokens

Synopsis

(factor, tokencount, type, value) = problem.getcoefformula (rowindex, colindex, parsed, bufsize)

Arguments

rowindex	The row index for the coefficient.
colindex	The column index for the coefficient.
factor	The value of the constant factor multiplying the formula in the coefficient.
parsed	Integer indicating whether the formula of the item is to be returned in internal unparsed format ( Parsed=0) or parsed (reverse Polish) format ( Parsed=1).
bufsize	Maximum number of tokens to return, i.e. length of the Type and Value arrays.
tokencount	Number of tokens returned in Type and Value.
type	Array to hold 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.
