Please help me make this easy plot work

1. f = exp(-0.5*x^2);
2. t = 0.5;
3. g_t = exp(-x-3t).^2;
4. h_t = exp(-x.^2+t).^2;
5. figure
6. hold all
7. plot(f,’r’)
8. plot(g_t)
9. plot(h_t,’g’)
10. xlim([25 60])
11. grid on

Error: File: plusen.m Line: 3 Column: 15 Unexpected MATLAB expression.

Please format your code in the question.

The error occurs because MATLAB does not recognize 3t as an expression. You need to use 3*t. (and define x as well but I guess you did it). And don't forget to use element-wise operations when dealing with arrays (eg .^ instead of ^ only).
