I have three different arrays a, b, c. I want to plot them in Matlab where c in the z axis and a and b in the x and y axis.
I mean I have a formula f(a, b) which I want to plot against a and b.

@Dev-iL: Thanks. I mean I have a formula $f(\alpha, \beta)$ which I want to plot against $\alpha$ and $\beta$. – applied_math Feb 03 '19 at 12:52

I assume you tried the obvious [`surf`](https://www.mathworks.com/help/matlab/ref/surf.html) function. How did that fail to meet your requirements? Did you try any other plotting functions? – beaker Feb 03 '19 at 17:05

If you want points, you can just use `plot3` or `scatter3`? – Wolfie Feb 04 '19 at 09:34

Have you tried meshgrid?
[a, b] = meshgrid(minA:stepA:maxA, minB:stepB:maxB);
c = myFunction(a,b);
surf(a,b,c);
Where a and b are in the ranges (minA,maxA) and (minB,maxB), respectively.
