Increasing the length of an array

Hello,

I have the following code line:

model_soot_ratio = ref_soot + ref_soot.(exp(soot_ratio)-1);*

The problem is as follows: ref_soot is a 70*1 array and exp(soot_ratio) is a 50*1 array. Hence the elementwise matrix multiplication is not possible which is what I need.

Is there any way to increase the size of the second array by adding say NULL elements at the end so that the multiplication is valid?

I am realtively new to Matlab programming, so any suggestions to improve will be highly appreciated.

Thank You.

A=[1 2 3 4 5 6]
B=[4 10];
B=[B zeros(1,numel(A)-numel(B))]

Or if you don't know which is the smaller

B1=[B zeros(1,numel(A)-numel(B))]
A1=[A zeros(1,numel(B)-numel(A))]

Heyy thanks for the quick response. I tried it and now my program works.
