API

``javascript
vqs = interp1(xs, vs, xqs);
vqs = interp1(xs, vs, xqs, method);
`

The function takes the following arguments:

- xs: Array of independent sample points. No value may occur more than once.
- vs: Array of dependent values v(x) with length equal to xs.
- xqs: Array of query points.
- method: Method of interpolation: linear, nearest, next or previous. Defaults to linear.

It returns an array of interpolated values vqs, corresponding to the query values xqs.

Example

`javascript
var vqs = interp1(
[1, 2, 3],
[-4, 6, 3],
[1, 1.5, 2.5],
'linear',
);
console.log(vqs);
// expected output: Array [-4, 1, 4.5]
`
