interp

Create an interpolated copy of the vector x.

Usage

interp(x, n, type {, mv})

x

vector to be interpolated

n

length of the interpolated output vector; the interpolated vector can be shorter or longer than the original

type

the type of interpolation to perform

type=0: linear interpolation

type=1: cubic spline interpolation

mv

the value to use for missing values. If mv is given, then interpolation is stopped when x[i] = mv. This means that the sections without missing values are individually interpolated. If mv is not supplied, the whole vector x is interpolated.

note: The missing value handling is implemented only for linear interpolation (type=0)

Result

The interpolated vector y with length n.
