@acer  Thank you

I want to do this，how can I do?

```restart;
Expr:=(2*I*Zeta*omega*omega[0] - omega^2 + omega[0]^2)*fourier(omega[r](t), t, omega) = (omega*B[1]*I + B[0])*fourier(delta(t), t, omega);
Expr/op([2,2],Expr)/op([1,1],Expr);```

@Kitonum  Hi，I  have another problem，If the number of the equation is (1), I don't want to rewrite the equation. I want to use the sequence number of the equation instead of the expression. How to do about the above problems?

Hi, I am puzzled that  I input codes in MAPLE as following，the result was ‘ x1= 1, x2 = 2, x3 = 3, x4 = 4, x5 = 5’，

restart;
L := [1, 2, 3, 4, 5];
seq(x[i] = L[i], i = 1 .. 5);

What is the function of assign?

@tomleslie  Thank you for your reply.  My question is whether  Maple has the same function, as the photo attached which was got from  MATLAB. Also, if has,how to operate?

@Carl Love  yes，use a mouse to pick up a point in a 3d figure.
