I have a 64x1 cell array that looks like this, I would like to vertically concatenate the cells in this array, and pad the rows with less columns with zeros ![blah.PNG](https://www.mathworks.com/matlabcentral/answers/uploaded_files/224422/blah.png)

maxcols = max(cellfun('size', NonC_tRNAs, 2)); %get the number of columns of the widest array
padded = cellfun(@(m) [m, zeros(size(m, 1), maxcols - size(m, 2))], NonC_tRNAs, 'UniformOutput', false); %pad each array
NonC_tRNAs_Reference = vertcat(padded{:})

Sorry if this is a dumb question, but what is "m" in this instance?
padded = cellfun(@(m) [m, zeros(size(m, 1), maxcols - size(m, 2))], NonC_tRNAs, 'UniformOutput', false); %pad each array

" what is "m" in this instance?"
An arbitrary name for the input variable of the anonymous function called by cellfun. It will be in turn each element of the same array.
