Vector as input for plotting function

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))

and what about the [sin(πx)]/[πx]?

Huh? Is it hard for you to type that? I should type that for you comeon! Make some effort!

doc sinc

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?

[madhan ravi]

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