i have an x and y matrix that are each 547x599 and a z matrix that has a time step (547x599x193). how do i make a loop that will plot each matrix for each of the 193 time steps using pcolor? (also using the pause command so it pauses before each plot)

Is this what you want?
for k = 1 : size(z, 3)
pcolor(z(:,:,k));
drawnow;
pause(0.3);
end

I have to plot the matrix’s globalx, globaly, and zb. Attached is the loop I tried but it didn’t work. Any ideas?

Use zzb{i} instead of, zzb(i)

In an assignment A(:) = B, the number of elements in A and B must be the same.
Error in xbeach (line 34) zzb(i)=zb(:,:,i);

You didn't do what he said - to use braces. You just used parentheses again. Looks like you really need to read the FAQ: https://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
Alternatively you can just use zb(:,:,i) like I showed in my answer. This extracts and shows just one slice/plane of the zb volumetric image.

I used the brackets and it gave the error that I posted. I’ll try what you said also.

Cell contents reference from a non-cell array object.
Error in xbeach (line 34) zzb{i}=zb{:,:,i};
