Extracting Multiple Points In Successive Images in a 3D Matrix

I have a 3D Matrix, say 100 x 100 x 25. These are 25 images, 100 x 100 each stacked on top of eachother.

The simplest version of what I am trying to achieve: Say I want to see how a point (say point [50,50]) of one of the images changes as a function of how the images progress. To clarify: this would make a 1D array, and if plotted would show how the values of that point change from image to image over 25 images.

I want to be able to track around 30 points, so I do not mind doing it manually for each point but a way to do it all at once would be great.

You would just build a 100 x 100 x 25 matrix (assuming these images are gray/binarized) and then something like:

figure;
plot(myImages(50,50,:));

Is there a more specific piece you need more help with?

I may have been unclear. I already have the 100 x 100 x 25 matrix, the matrix is composed of 25, 100 x 100 images. These images are stacked on top of eachother. I want to be able to track a single point on one of those images, across all 25 images.
