How to do scatter/plot overlaying an imagesc/pcolor plot?

I have a matrix (200 x 200), which I do: imagesc(v(1:200),v2(1:200), matrix); This is an extrapolated Matrix, and now I wish to scatter / plot my data point observations locations on top of this matrix field.
How would I go about doing this? I thought maybe I could imagesc a matrix of the scattered observation with increased transparency? but I guess there must be a better way to do this..

Don't use pcolor() unless you're happy not displaying the last row and column of your image.
To overlay one image on top of another, see these links:
To plot or scatter points, then just call hold on and then scatter() or plot():
imshow(yourImage);
hold on;
plot(x,y, 'rd', 'MarkerSize', 30); % Plot red diamonds over image.

The general idea should be the same whatever function you are using to plot your image data.
