Plot Problem

These commands create the expected plot:

x=.1:.1:4*pi;
y=sin(pi*x)/pi;
plot(x,y)

However, the following commands create a horizontal line at zero:

x=.1:.1:4*pi;
y=(sin(pi*x))/(pi*x);
plot(x,y)

(I don't have a sinc function.) I don't understand why the second set of commands doesn't work. Thoughts?

Answer 1

[Walter Roberson]

You are using mrdivide when you want to use rdivide

[Rick]

y=(sin(pi*x))./(pi*x); gives expected plot. Thanks.

Answer 2

[Raviteja]

x=.1:.1:4*pi;
y=(sin(pi*x))./(pi*x);
plot(x,y)

Is this working?
