T = 2           % Given a number T
T = 2
T^-1            % T^-1 is 1/T
ans = 0.5000
m=1:24*(T^-1)   % m is from 1 to 24/T=12 with default step of 1
m = 1×12

In context, is T a scalar floating point value that is expected to be less than 1 ?

If so, then the code would be equivalent to

m = 1 : 24./T;

which would be equivalent to

m = 1 : floor(24./T);

which would be the list of integers, 1, 2, 3, 4, ... up to floor(24./T)

The reason for the code is not clear. In most cases in which something that looks like this might be used, the variable T would instead be named Fs or FS or fs (frequency of sampling) or else f (frequency). T tends to suggest a time, and it would be uncommon to want to do something until the inverse of a time.
