How do I apply a function with multiple parameters using `cellfun` (MATLAB)?

Using cellfun, how do I apply a function to all the cells created by the mat2cell function? My function is defined in another file, here it is referred to by myFunc. This function takes two arguments, which should be a cell and an integer.

e.g. function H = myFunc(img,Q)

My code is as follows:

% Split into grid and process each cell
width = size(img,2) % get image width
height = size(img,1) % get image height
depth = size(img,3) % get depth
C = mat2cell(img,[height/2 height/2],[width/2 width/2],[depth/2 depth/2]); % divides image into sections
F = cellfun(@myFunc,C);
save(fout,'F');

The issue is of course with the line F = cellfun(@myFunc,C);. How do I pass the cells and a chosen integer e.g. 4 into myFunc for each cell?

Many thanks.

Solution

  • Well, simply define a new anonymous function as @(x) myFunc(x,4) and use it this way:

    F = cellfun(@(x) myFunc(x,4), C)
