Dear all,

I ran these commands in Maples:

restart:

x:=Matrix([[x1],[x2]])

W:=<<w11 | w12>, <w21 | w22>>

v:= (W.x)

f:=(W.x)^%T.(W.x);

eq1:=<seq(diff(f,t),t=x)>;

eq2:=2*W^%T.v;

seq(is(eq1[i] = eq2[i]), i=1..numelems(eq1))

Then, I got this answer:

false, false

However, eq1 is the same as eq2, thus I expected to get 'true,true'.

Would you tell me what went wrong?

Thank you
