Hello, I have a cell array of images obtained by scanning in a raster scan as illustrated below
I want to create a montaged image, and can do it successfully when xsteps & ysteps =3 (so 9 images in the image Array "imgArray")
montageImage = [imgArray{1}, imgArray{4}, imgArray{7}; imgArray{2}, imgArray{5}, imgArray{8}; imgArray{3}, imgArray{6}, imgArray{9}];
However, I want it generalised for any values of xstep and ystep.

Read about montage in the documentation, there is an option of specifying size..with this you can show them in your desired step/ size.
https://in.mathworks.com/help/images/ref/montage.html
montage(fileNames, 'Size', [m n]);

If images are present, filenames are enough to show.

Hi, so they are saved in appdata and I get the cell array of images by:
imgArray=getappdata(0,'stack')
What do I pass as filenames, just "imgArray"
OK trying this doesn't work:
figure
montage(imgArray, 'Size', [3 3]);
The specified filename is not a string.

OK, I couldn't get the "montage" function to work so used this instead
ny=ysteps; nx=xsteps;
D=[];
for j=1:ny
C=[];
for i=1:nx
idx=1+ (i-1)*ny;
idx=idx+(j-1)
B=imgArray2{idx};
C = horzcat(C,B);
end
D=vertcat(D,C);
end
figure
imshow(D)
