problem with symbolic expression
Posted:
Jul 19, 1996 12:59 AM


Can anyone tell me what I did wrong? I tried to integrate cos(pi*t/5)^2 (which is the same as multiplying cos(pi*t/5) with its conjugate) from a to a while a is from 0 to 30.

x1 = sym('cos(pi*t/5)'); y1 = sym('conj(x1)'); integx1 = symmul(x1,y1); E1 = int(integx1,'a','a'); a = 0:30; ezplot(E1)  I got the message
??? Error using ==> ezplot Symbolic variable not uniquely determined.
I have no idea what causes this problem.
