Hello,
i would like to plot with red stars the function: sinc(x)= [sin(πx)]/[πx]
but x would be a vector given by the user
I really dont know how to ask the user to give me the vector and how can i use it as input for my function.

x = input('Values of x:') % feed in for example [1,2,3]
y = @sinc;
plot(x,y(x))

No, i mean that it goes:
x = input('Values of x:') % feed in for example [1,2,3]
y=@sinc;
sinc= [sin(πx)]/[πx];
plot(x,y(x))
right?

clear sinc
y = @(x) sin(pi*x) ./ (pi*x);
