Hello all,
A seemingly simple question but I just cant find an answer to it.
array_counter_a=1;
for a=0:1:30
array_counter_b=1;
for b=0:1:30
solution(array_counter_a,array_counter_b)= some_function(a,b)
array_counter_b = array_counter_b+1;
end
array_counter_a=array_counter_a+1;
end
a=0:1:30;
b=0:1:30;
So 'a' is a variable of size 30x1, 'b' is a variable of size 30x1, and the size of solution is the size of 30x30. Now i want to 3d plot of solution vs 'a' and 'b'. I always get an error saying dimensions mismatch, but i dont understand why.

%if true
mesh(0:30,0:30,solution)
Try the above. If you have used
%if true
mesh(a,b,solution);
It won't work. Since a and b are for loop counters. So at end of loop their values are just 30 and 30.

It works with mesh, instead of plot3. However it works, and I got what i needed. Thank you.
