Interpolation

Interpolation

Operation that consists of constructing or estimating the value of a function for a value of the variable taken between two discrete values in the interval in which the relationship was established.

Example

Starting from the values of $$\log(5)$$ and $$\log(6)$$, we can estimate using interpolation the value of $$\log(5.5)$$:

$$\log(5.5) ≈ \log(5) +\dfrac{\log(5) + \log(6)}{2} ≈ 0.738$$.
