960	Inconsistent behaviour of functions MatMin, MatMax, VMatMin, VMatMax with matrices containing unknown values	lcereceda	Víctor de Buen Remiro	"When dealing with matrices containing unknown values, the behaviour of the functions MatMin, MatMax, VMatMin, VMatMax is inconsistent.

For

{{{
Matrix a = Col( 1, ?, 2 );
Real a.min = MatMin(a);
Real a.max = MatMax(a);
VMatrix va = Mat2VMat(a);
Real va.min = VMatMin(va);
Real va.max = VMatMax(va);
}}}

we obtain real numbers, while for

{{{
Matrix b = Col( ?, 1, 2 );
Real b.min = MatMin(b);
Real b.max = MatMax(b);
VMatrix vb = Mat2VMat(b);
Real vb.min = VMatMin(vb);
Real vb.max = VMatMax(vb);
}}}

we obtain unknowns."	defect	closed	high	Mantainance	Kernel	2.0.1	critical	fixed	MatMin, MatMax, VMatMin, VMatMax
