Is there a method to sort a list an array of words alphabetically (natural order sorting)
>> sort({'gamma', 'delta', 'alpha', 'beta'}) ans = 'alpha' 'beta' 'delta' 'gamma'

How do you create a loop to find a coefficient value to which one of the variables in the function changes with every cycle
The first thing to be clear about is the distinction between the time step, dt, and the time itself, which might be called t. dt...
