Sinc function.

📝 Syntax

• c = sinc(m)

📥 Input argument

• m - input array: scalar, vector or matrix.

📤 Output argument

• c - sinc of input

📄 Description

c = sinc(m) returns an array c whose elements are the sinc of the elements of the input: m.

The sinc function (normalized) is defined as: $\text{sinc}(x) = \begin{cases} \frac{\sin(\pi x)}{\pi x} & \text{if } x \neq 0 \\ 1 & \text{if } x = 0 \end{cases}$

The sinc function is the Fourier transform of the rectangular pulse function and appears frequently in signal processing and communications.

💡 Example
