User Defined Montage but filling 12x8 Array

Hello, I am scanning a sample that has a possible 12x8 locations. The user defines the positons to scan and the scan order is indicated by the number in the cells
I have a 1D cell array containing the images from the scan
I also have the row and col locations for each image
row=app.Positions(:,1) %column 1 for row locations
col=app.Positions(:,2) %column 2 for col locations
Whats the best way to create a montage splatting the images in the montage reflecting the positon in the table. For each image i have the row and col positons they were captured in. I would like to always display a 12x8 montage and just put positions where no image was created to e.g. blank (zero)
This was my attempt.
%First create "blank" images of zeros and position in all 12x8 locations
[sy,sx]=size(app.imgArray{1}) % Get size of each image, just used the 1st one as the size doesnt change
B=zeros(sy,sx); %Create a blank image
for j=1:8
for i=1:12
M(i,j)=B; %create a 12x8 array of blank images
Now positon the real images at their repsective locations
for i=1:m %m is the number of images
r=row(i); c=col(i);
But I can't get passed creating the montage of blank images:
Error in HPBR/montage (line 1402)
