How to subtract coloumn vectors of a cell array

Dear Community,

I have a cell array, with each cell containing n by m matrix. I would like to use cellfun and minus, and subtract the first coloumn from the second one, and add the value of 1. (like: result=(second coloumn-first coloumn)+1)

Unfortunately I do not exacty understand the nature of cellfun, to solve this.

Please find attached an example cell, and a result.mat showing, what would I like to get, when perform the calculation in the first cell.

Many thanks for you suggestions!

inp = load('mycell.mat').mycell; % input data
fun = @(m) 1+diff(m,1,2); % anonymous function
out = cellfun(fun,inp, 'uni',0) % calculate

out = 12×1 cell array
    {100×1 double}
    {100×1 double}
    {100×1 double}
    { 20×1 double}
    { 20×1 double}
    { 20×1 double}
    {124×1 double}
    {124×1 double}
    {124×1 double}
    {101×1 double}
    {101×1 double}
    {101×1 double}

out{1} % compare first cell against expected output

ans = 100×1

10 23 34 17 13 3 512 4 10 37

load('result.mat').result

ans = 100×1

10 23 34 17 13 3 512 4 10 37
