Hi,
Could you please tell me how to increase number near "a" so it could look like this:
b = 1; "ab = something" b = b + 1; ...
a1 = something; a2 = something; ... an = something;

What do you mean?

Please don't use dynamic variable names, matlab has plenty of options to store your data in a better way. Use cells or structs.

If the "a" are being assign to simple numbers (not to strings, structures, cells, etc.), then using a simple numerical array is best and easiest:
for k = 1 : 118
a(k) = b; % a is floating point array, unless you explicitly cast b to an integer type.
b = b + 1; % Whatever.....
end
