problem.getccoef
problem.getccoef |
Purpose
Retrieve a single matrix coefficient as a formula in a character string
Synopsis
(factor, formula) = problem.getccoef (rowindex, colindex, flen)
Arguments
|
RowIndex
|
Integer holding the row index for the coefficient.
|
|
ColIndex
|
Integer holding the column index for the coefficient.
|
|
Factor
|
Address of a double precision variable to receive the value of the constant factor multiplying the formula in the coefficient.
|
|
Formula
|
Character buffer in which the formula will be placed in the same format as used for input from a file. The formula will be null terminated. |
|
fLen
|
Maximum length of returned formula.
|
Return value
|
0
|
Normal return.
|
|
1
|
Formula is too long for the buffer and has been truncated.
|
|
other
|
Error.
|
Example
The following example displays the formula for the coefficient in row 2, column 3:
(factor, formula) = p.getccoef (2, 3, 60)
Further information
If the requested coefficient is constant, then factor will be set to 1 and the value will be formatted in formula.
If the length of the formula would exceed flen - 1, the formula is truncated to the last token that will fit, and the (partial) formula is terminated with a null character.
