Importing code from octave to matlab

Hello, i've got a problem with MatLAB when trying to run a code that i've written in octave.

The code in octave works perfectly but when i run it in MatLab it doesnt work, how can i write this line so it works in matlab?

The error message is: ` Invalid array indexing.`

z = abs(fft(c))(1:T*fs/2)/(T*fs);

tmp = abs(fft(c));
z = tmp(1:T*fs/2)/(T*fs);
