[catmat]=padconcatenation(a,b,c)
concatenates arrays with different sizes and pads with NaN.
a and b are two arrays (one or two-dimensional) to be concatenated, c must be 1 for
vertical concatenation ([a;b]) and 2 for horizontal concatenation ([a b])

a=rand(3,4)
b=rand(5,2)
a =

0.8423 0.8809 0.7773 0.3531
0.2230 0.9365 0.1575 0.3072
0.4320 0.4889 0.1650 0.9846
b =

0.6506 0.8854
0.8269 0.0527
0.4742 0.3516
0.4826 0.2625
0.6184 0.5161

PADab=padconcatenation(a,b,1)
PADab =

0.4742 0.3516 NaN NaN
0.4826 0.2625 NaN NaN
0.6184 0.5161 NaN NaN
