Im trying to plot the sinc function and im given my A and T however when i try to input the equation i get an error
A = 1;
T = 1;
gf= AT sinc(fT);

If you want to plot the sinc value for a range of values then you need to pass it a vector of values.
So for example:
x = linspace(-10,10,1000); % defines a vector with a thousand equally spaced points between -10 and 10
y = sinc(x);
You will need to modify with your actual values and scaling constants

If you are still just trying to get the basics of using MATLAB I would suggest completing the MATLAB on-ramp https://www.mathworks.com/learn/tutorials/matlab-onramp.html

Hi, try it this way. That is the way how it should be done. But I could not get the exact waveform. Maybe others could help.
t = linspace(-5,5);
y = A.*t.*sinc(f.*t);
