Interpolation of matrices corresponding to time vector

1 次查看(过去 30 天)
I have a vector containing time points, and a cell structure containing matrices as its elements.
I want to interpolate the corresponding matrix for some time point which is not in the time vector. How to do that?

Or, depending on sizes, it might be more efficient to interpolate all matrix components at the same time with interp3, or interpn. The different interpolation functions have slightly different options when it comes to interpolation methods.

Variant with interp1:
t = [1, 2, 3];
A = {[1, 1; 1, 1] ,[1, 0.9;0.95, .87] , [1.1, 0.85;0.91, .8]};
tt = [1.2, 2.1, 2.9];
out = interp1(t(:),permute(cat(3,A{:}),[3,2,1]),tt);
out = permute(out,3:-1:1);
