Check for missing argument or incorrect argument data type in call to function 'sinc'.

x = linspace(-4*pi, 4*pi, 100)

P = (3*pi)/2

plot(x, P*sinc(x) + cos(x))

grid

This is my code. I am not sure why it is showing an error.

Error:- Check for missing argument or incorrect argument data type in call to function 'sinc'.

Answer 1

x = linspace(-4*pi, 4*pi, 100)
P = (3*pi)/2
plot(x, P*(sin(x)./x) + cos(x))
grid

Using this instead of sinc function solved the issue.
