I have an NxMxP matrix that forms a volume. Programs like ImageJ have a function to save the XY coordinates of any pixels above a certain threshold, is there a good way to implement this in 3D in matlab?

Try something like this
M = randi([0 5], 20, 30, 10); % example matrix
idx = find(M); % find nonzero values in M
[y,x,z] = ind2sub(size(M), idx);
y is the row number, x is column number, and z is the 3D slice number of non-zero entries.
