Linear interpolation in a buffer of random values
Information
Syntax
y = Linear.interpolate(buffer,offset);
Description
Interpolate in buffer by using linear interpolation. Input argument offset is a Real number marking the point at which interpolation shall take place. offset=0 is the first buffer value buffer[1]. offset=size(buffer,1)-1 is the last buffer value buffer[size(buffer,1)]. It is required that 0 ≤ offset < size(buffer,1)-1. The function returns the lineraly interpolated value. In order to avoid issues at the end of the buffer (where a minimally too large offset value triggers an assert), it is best to make the buffer one element larger as needed. For example, if the buffer is filled with a sample period of 1 ms and every 100 samples an event occurs, then the buffer should have length 102 for the samples 0 ms, 1 ms, 2 ms, ...., 100 ms, 101 ms.
