MATLAB: Resize 4-dimensional matrix, possible

interpolationMATLABparallel computing

I have a simple question.

I have a function F(a,b,c,d) with dimension=50 each. It represents a set of optical transfer functions and I'm curious if there is any way to interpolate this 4-D Matrix using matlab.

Calculating it takes lots of time, which brought me to this – perhaps stupid – question.

Thank you very much for your thoughts!

Try interpn, which interpolates any number of dimensions.

Given your input criteria, you can simply reshape C:

sz = size(C, 2);
C = reshape(C, 3, 3, sz/3); 
D = arrayfun(@(i)A*B*C(:,:,i), 1:sz/3, 'UniformOutput', false);

MATLAB: Command to reshape matrix diagonally

% X - array with size [5541888 x 7]
% m2 - number of rows in second array, m2 = 1536
[~,n] = size(X);
out = reshape(permute(reshape(X',n,m2,[]),[1 3 2]),[],m2)';

[m,n] = size(X);
a = mat2cell(X,m2*ones(m/m2,1),n);
out = [a{:}];
