Question about representation of data in Matlab

[Frank Einstein]

Hi everybody; I have plotted a matrix with sea surface temperature's correlation with another variable, the size is (360x180x12); using to plot :

figure
for i=1:12
subplot(4,3,i);imagescnan(loni,lati,squeeze(double(r4_sat(:,:,i)))'),colorbar;
end

Now, I want to plot over it another matrix of the same size which contains the same data but only when it is significative; I think the comand quiver would be suitable for this, but when I try to use it, there is an error.

figure
for i=1:12
subplot(4,3,i);imagescnan(loni,lati,squeeze(double(r4_sat(:,:,i)))'),colorbar;
hold on
subplot(4,3,i); quiver(loni,lati, r4_sat_sign(:,:,i), r4_sat_sign(:,:,i));
end

The error comes from the fact that I need to have the same size for all four variables, but I don't know how to manage it.

Can someone please tell me how to properly use quiver here or sugest an alternative?
Thanks for reading.

Have you looked at the docs page for quiver? https://www.mathworks.com/help/matlab/ref/quiver.html
