How do you interpolate on a log scale?

Just replace all y values by log(y) and all x-values by log(x). That's all. That's exactly what a log-log plot does. Your result is then log(y), but of course you can recover y using y = exp(log(y)).

What is interpolation method in Python?

Interpolation in Python is a technique used to estimate unknown data points between two known data points. Interpolation is mostly used to impute missing values in the dataframe or series while preprocessing data.

How do you make interpolation faster in Python?

The simplest solution is to use something which can be vectorized. eg. ynew = function(xnew);simps(ynew,xnew) This is much faster, but depending on the inputs less accurate.

What is interp1d in Python?

The interp1d() function of scipy. interpolate package is used to interpolate a 1-D function. It takes arrays of values such as x and y to approximate some function y = f(x) and then uses interpolation to find the value of new points.
