hi
I want to move my "sinc" function from negative to positive side. The function is;
t=-40.955:0.005:40.960;
u=(200/pi)*(15*sinc(15*t)-3*sinc(3*t));
It needs to start from "0". would you please help me with that? how can i move my axis in "sinc" function
like this plot. Thanks in advance.

To move it in the plot, simply add the appropriate value to the ‘t’ vector:
t=-40.955:0.005:40.960;
u=(200/pi)*(15*sinc(15*t)-3*sinc(3*t));
figure
plot(t-min(t), u)
grid
Experiment to get the result you want.
