Hello,
I have the above named error all the time, but I can't see the dimension problem.
-------------------------------
figure
x=[1:31];
y=[1:5];
[X,Y]=meshgrid(x,y);
Z=Price(x,y);
mesh(X,Y,Z)
xlabel('Stock Price')
ylabel('Sigma')
zlabel('Call Price')
-------------------------------
"Price" is a 31x5 matrice. I tried also playing with m x n changes of all inputs but nothing did work so far.
Thank you a lot for your help.

If you are getting "index exceeds matrix dimensions" on the mesh() call, then likely you have accidentally created a variable named "mesh".
Note: if x and y are those vectors then Price(x,y) would be the same as Price by itself, and there would be no reason to use meshgrid(). Just mesh(Price);

I do not get "Index exceeds matrix dimension": I get "data dimensions must match".
Change your meshgrid() to ndgrid()
