CODE:
%% Testing Phase
load('testFeatures');
featvales=b2{1};
label=b2{2};
num_dims = max(size(featvales));
X=featvales';
Y=label';
PROBLEM:
I have to calculate the average for 2 different dimension
1st for 10 dimensional function
2nd for 30 dimensional function
ERROR :(the following error is recieved while executing the code)
Error using '
Transpose on ND array is not defined. Use PERMUTE instead.
Error in FeatureSelection (line 28)
X=featvales';

Ran in:
The error message is clear. How do you transpose a three (or more) dimension array?
a=rand(2,3);
a';
a=rand(2,3,4);
a';
Error using '
TRANSPOSE does not support N-D arrays. Use PAGETRANSPOSE/PAGECTRANSPOSE to transpose pages or PERMUTE to reorder dimensions of N-D arrays.

If you are trying to transpose the initial 2D pages of your variable, you can do this:
pagetranspose(featvales)
Or this:
d = 1:ndims(featvales)
permute(featvales,[2,1,d(3:end)])
But it isn't clear if this will fix your underlying problem.

what exactly does this output gives as output?
it is showing a value for (:, :, 1, 704) to (:, :, 1000, 704)
