# diric

Generate the Dirichlet function.

## Syntax

d = diric(x, n)

## Inputs

`x`- The values at which to evaluate the function.
`n`- The Dirichlet kernel index.

## Outputs

- d
- The diric values.

## Example

Generate five periods of the diric function with index 9.

```
x = [0:0.01:5]*(2*pi);
d = diric(x, 9);
plot (x, d);
xlabel('time');
ylabel('amplitude');
```

## Comments

The Dirichlet function is also knows as the periodic sinc function.
