XSLPgetccoef, XPRSslpgetccoef

Purpose
This subroutine is deprecated and will be removed in a future release. Use XPRSslpgetcoefstr instead.
Retrieve a single matrix coefficient as a formula in a character string. For a simpler version of this function see XPRSnlpgetformulastr.
Synopsis
int XPRS_CC XSLPgetccoef(XSLPprob prob, int row, int col, double *p_factor, char *formula, int maxbytes);
Arguments
prob 
The current SLP problem.
row 
Integer holding the row index for the coefficient.
col 
Integer holding the column index for the coefficient.
p_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.
maxbytes 
Maximum length of returned formula.
Return value
0 
Normal return.
32 
formula is too long for the buffer and has been truncated.
other 
Error.
Example
The following example displays the formula for the coefficient of column 3 in row 2: 
char Buffer[60];
double factor;
int Code;

Code = XSLPgetccoef(prob, 2, 3, &factor, Buffer, 60);
switch (Code) {
case 0:  printf("\nFormula is %s",Buffer);
         printf("\nFactor = %lg",factor);
         break;
case 32: printf("\nFormula is too long for the buffer");
         break;
default: printf("\nError accessing coefficient");
         break;
}
Further information

If the requested coefficient is constant, then p_factor will be set to 1.0 and the value will be formatted in formula.

If the length of the formula would exceed maxbytes-1, the formula is truncated to the last token that will fit, and the (partial) formula is terminated with a null character.
