Synopsis
`int XPRS_CC XPRSclearrowflags(XPRSprob prob, const int flags[], int first, int last);`
Arguments

prob | The current problem
flags | Integer array of length last-first+1 including type of extra information to remove (see below)
first | First row index to be checked
last | Last row index to be checked

Example
The following makes sure that the second and third rows are not indicators and removes any quadratic matrix from the second row.

    int flags[2];
    int flags[2];
    flags[0] = XPRS_ROWFLAG_QUADRATIC+XPRS_ROWFLAG_INDICATOR;
    flags[1] = XPRS_ROWFLAG_INDICATOR;
    XPRSclearrowflags(prob,1,2,flags);

Further information
The flags array consists of a bitvector for each row defining types of information to remove:

XPRS_ROWFLAG_QUADRATIC
  Remove all quadratic coefficients.
XPRS_ROWFLAG_DELAYED
  The row will not be a delayed row.
XPRS_ROWFLAG_MODELCUT
  The row will not be a model cut.
XPRS_ROWFLAG_INDICATOR
