Interp2(_, method) function specifies an alternative interpolation function such as ‘linear’, ‘nearest’, ‘cubic’, ‘makima’, or ‘spline’. This results in 2^k-1 interpolated points between sample values. Interp2(V, k) function is used to return the interpolated values on a refined grid formed by repeatedly halving the intervals k times in each dimension. Interp2(V) function is used to return the interpolated values on a refined grid formed by dividing the interval between sample values once in each dimension. These points cover the rectangular region, X=1:n and Y=1:m, where = size(V).
Interp2(V, Xq, Yq) function is for the default grid of sample points. Here the coordinates of the sample points reside in “X” and “Y”, “V” contains the corresponding function values at each sample point, and “Xq”, “Yq” contains the coordinates of the query points. Its result passes through the original sampling of the function. Interp2(X, Y, V, Xq, Yq) function is used to return interpolated values of a specified function of two variables at specific query points using linear interpolation. The interp2() function is used to Interpolate for 2-D gridded data in a mesh grid format.
