Purpose

Used to change the type of a row in the matrix.

Synopsis

int XPRS_CC XPRSchgrowtype(XPRSprob prob, int nels, const int mindex[], const char qrtype[]);

Arguments

prob	The current problem.
nels	Number of rows to change.
mindex	Integer array of length nels containing the indices of the rows.
qrtype	Character array of length nels giving the new row types: L  indicates a row; E  indicates an = row; G  indicates a row; R  indicates a range row; N  indicates a free row.

Example

Here row 4 is changed to an equality row:

mindex[0] = 4; qrtype[0] = "E";
XPRSchgrowtype(prob,1,mindex,qrtype);

Further information

A row can be changed to a range type row by first changing the row to an R or L type row and then changing the range on the row using XPRSchgrhsrange.
