Simple explanation to Linear Interpolation
Posted: Fri May 07, 2010 3:38 am
I would get a simple example to explain linear interpolation.
Say we have 2 pairs of associated values denoted as (x1, y1) and (x3, y3). We know a number x2, which is between x1 and x3. We need to find the corresponding value of x2, which is denoted by y2.
The technique we use here to get the value of y2 is called linear interpolation.
y2 can be derived as below,

| x1 | y1 |
| x2 | y2 |
| x3 | y3 |
y2 can be derived as below,
