### Parameters

- `x` : real or complex vector or matrix
- `t` : real or complex vector or matrix

### Description

If `x` is a vector or a matrix, `t=sinc(x)` is the vector or matrix such that `t(i)=sin(x(i))/x(i)` if `x(i)~=0` and `t(i)=1` if `x(i)==0`

### Examples

    x=linspace(-10,10,3000);
    plot2d(x,sinc(x))
