<refpurpose>This function finds a solution for linear equation Ax = b over a prime Galois field.</refpurpose>
</refnamediv>

<title>Description</title>
<para>
[X, SFLAG] = GFLINEQ(A, B) returns a particular solution (X) of AX=B in GF(2).
If the equation has no solution, then X is empty and SFLAG = 0 else SFLAG = 1.
</para>
<para>
[X, SFLAG]= GFLINEQ(A, B, P) returns a particular solution of the linear
equation A X = B in GF(P) and SFLAG=1.
If the equation has no solution, then X is empty and SFLAG = 0.
