What does interp1 do Matlab?

Description. vq = interp1( x , v , xq ) returns interpolated values of a 1-D function at specific query points using linear interpolation. Vector x contains the sample points, and v contains the corresponding values, v(x). Vector xq contains the coordinates of the query points.

What does interp2 do in Matlab?

Vq = interp2( X,Y , V , Xq,Yq ) returns interpolated values of a function of two variables at specific query points using linear interpolation. The results always pass through the original sampling of the function.

How to do linear interpolation in Matlab?

The function to perform linear interpolation, MATLAB provides the interp1() function. Here, a sample point is a set of data points, which could be an array or a vector. The value of the unknown function on sample points is also a set that has the same size/length as the sample points.
