a = 1:45;
reshape([a(:);nan(mod(-numel(a),4),1)],4,[])';

The mod() expression figures out how many values need to be added to bring the total number of values up to a multiple of 4, and the nan() part of it says to create a vector that many elements long each element of which is nan (Not A Number). The effect of the code is to pad out the array to be a multiple of 4 long, by adding as many nan on the end as needed to make a multiple of 4.
