Hello,
When using the default trilinear interpolation of interp3, I'm getting an unexpected output:
>> Interpval = interp3(X,X,X,V,X(10),X(5),X(1))Interpval = 2.373878950731685e+04>> V(10,5,1)ans = 2.423129551369272e+04
where X is an n x 1 vector, and V is an n x n x n matrix.
I expected the two results to match as it should notice that the interpolation point is a grid point.
Why do the results not match?
Hopefully I'm just tired and this is a trivial question.
Thanks for your time and help.
