Hi,

I am using the function simplify in order to simplify some big expressions I have. The poblem is:

I have the expression F=F(x1,x2,x3,......,xn)  and if I evaluate the two following expressions

expr1 = subs(x1=a, x2=b, x3 =c , .......,xn=d, F) = F1    (scalar)

expr2 = subs(x1=a, x2=b, x3 =c , .......,xn=d, simplify(F) ) = F2    (scalar)

Normally F1 and F2 are equal  ( F1=F2 ) but what I really get...
