I want to draw surf plot for the attached figure

The c=4 and alfa=3.2.T is vector from -0.5 to 0.5.X is vector from 4 to -4

Hi @Tarek

You can find little examples in the surf() documentation. Were you provided with (i) a surface equation, (ii) parametric equations, or (iii) an implicit equation that contains the parameters 'c' and 'alfa', but you are unsure how to implement this in MATLAB due to lack of examples?

@Tarek,

You did not attach a figure. But let's suppose that you compute a function f(X,T), on a grid of X and T values.

x=-4:0.2:4; t=-0.5:.025:+0.5;
[X,T]=meshgrid(x,t);
f=exp(-((X/2).^2+(T/.25).^2));
surf(X,T,f,'EdgeColor','none');
colorbar
xlabel('X'); ylabel('T'); title('f(X,T)')
