matlab change upper case character to lower case character in string

I would like to take a string and change the first letter of that string from upper to lower case in MATLAB. Any suggestions. Example:

a = 'Upper'; % Do something to a a = 'upper'

a = lower(a);

If you only need to change the first letter to upper case, try the following:

a = [lower(a(1)) a(2:end)];

That will convert the whole string to lower case as opposed to only the first letter, which what the OP is after. It turns out that it works just fine for his example, but consider for example UppeR : that would give you upper instead of uppeR .
