how to make numbering near "a" like: a1, a2, an

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;

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

I second Arthur's suggestion: Do not insert an index in the name of the variable. While this might look useful for "a1", "a2", "a3", it becomes a horror for ..."a117", "a118" etc. Using "a{1}", "a{2}" is much smarter.

There is a run of these requests recently.

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

for example_:

    % for i=1:2:5
b=['a_'  num2str(i)]
end

is that waht are u looking for?
