Interpolation between two surfaces with same grid
显示 更早的评论
I have two different matrices (or surfaces) of the same size which also use the same XY grid. I want to interpolate between these two matrices to create another matrix. Since they already have the same grid I don't how I could apply the 'interp' command to this problem.
I found a related Q&A here: https://de.mathworks.com/matlabcentral/answers/231424-how-to-interpolate-between-two-3d-shapes
But to me it is very important to be able to chose the inter- and extrapolation method.
A simple example:
[x,y] = meshgrid(-4:4,-4:4);
M1 = magic(4)./4;
M2 = fliplr(M1)-4;
