Is there a sinc function in Matlab?

Description. y = sinc( x ) returns an array, y , whose elements are the sinc of the elements of the input, x . The output y is the same size as x .

How do you write x2 in Matlab?

For example, you might write x. ^2 in another way, using x. *x. This would effectively square every element in the vector x.

How do you plot a sinc function?

The sinc function is the continuous inverse Fourier transform of the rectangular pulse of width and height 1. for all other elements of x . To plot the sinc function for a linearly spaced vector with values ranging from -5 to 5, use the following commands: x = linspace(-5,5); y = sinc(x); plot(x,y)

How do you create a sine function in Matlab?

Y = sin( X ) returns the sine of the elements of X . The sin function operates element-wise on arrays. The function accepts both real and complex inputs.
