I’m not too sure what you’re looking for but, if you want to create an image grid from individual slices you can arrange each slice into a single large grid using matrix manipulation and plotting functions. I’m going under the assumption that each slice is a 2D matrix which is to be displayed in a grid format.

% Number of rows and columns for the grid
numRows = 4; % Example: 4 rows
numCols = 4; % Example: 4 columns

% Assuming `slices` is a cell array where each cell contains a slice (2D matrix)
slices = {}; % Your slices data should go here

% Example dimensions of each slice (height x width)
[height, width] = size(slices{1});

% Create an empty matrix to hold the full grid
fullGrid = zeros(height * numRows, width * numCols);

% Loop over each slice and place it into the full grid
for i = 1:numRows
    for j = 1:numCols
        % Calculate the starting row and column indices for the current slice
        startRow = (i-1) * height + 1;
        startCol = (j-1) * width + 1;
        
        % Extract the current slice from the cell array
        currentSlice = slices{(i-1)*numCols + j};
        
        % Place the slice into the full grid
        fullGrid(startRow:startRow + height - 1, startCol:startCol + width - 1) = currentSlice;
    end
end

% Display the full grid
imagesc(fullGrid);
axis equal;
colormap gray; % Use grayscale colormap or modify as needed
colorbar; % Display a colorbar if needed
title('Image Grid of Slices');

You just need to set your grid size by altering the numRows and numCols depending on your specification.

Create your empty matrix (fullGrid) to the appropriate size to hold your slices.

Loop over each slice, compute its position in the final grid and insert it into its respective location.

The imagesc just visualizes your grid and the colormap function is used to display the color as shown in your attached link. The colorbar is just there to display the color scale.
