I don't know what is your aim by doing this, but it seems it's a bad idea

Just call it ‘a_b’.

For example:

a_b = a + b;

As a general rule, it is best to use numeric or cell arrays to name what might be best considered to be elements of arrays (so ‘c(k)’ or ‘c{k}’ is the correct way to create a new variable as part of an array, and ‘c_k’ is quite definitely not the correct way), variables are best named to be as descriptive as possible.

For example:

mean_a_b = mean(a.*b);

is better than:

a_b = mean(a.*b);
