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...
