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);

Please copy and paste the full error message, all of the red text, so we can see what error you are getting.

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);
plot(x,y)
You will need to modify with your actual values and scaling constants

By the way the error message you are getting is because you didn't have a multiplication operator. You need to have something like:
gf = A*T*sinc(ft)
This would have then given another error, because you have not yet defined ft

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);
f=1./t;
A=5;
y = A.*t.*sinc(f.*t);
plot(t,y)
grid
