Matlab transpose values in a structure within a cell array

Question

I successfully created a moving window of n=85 for my data and put the windows in a cell array:

n = 37886;
cell_array=cell(n,1);
a = 1:n;
for T=1:n-84
  M=a(T:T+84);
    tmpstruct=struct('M',M);
    cell_array{T}=tmpstruct;
end

However, I need to transpose M, which is the data of window values located within the structure within the cell array. That is, instead of the vector of window values being 1x85, I want them to be 85x1.

I've attempted transposing with this:

cell_array = cellfun(@transpose,cell_array,'UniformOutput',false);

But this code doesn't work for me.

Any feedback on how to transpose my windows will be greatly appreciated. I need to transpose 252 cell arrays, so doing this manually is out of the question.

If I clearly understood, what about:

n = 37886;
cell_array=cell(n,1);
a = 1:n;
for T=1:n-84
  M=a(T:T+84);
    tmpstruct=struct('M',M'); % Modified line to transpose windows!
    cell_array{T}=tmpstruct;
end

If you prefer named functions:

n = 37886;
cell_array=cell(n,1);
a = 1:n;
for T=1:n-84
  M=a(T:T+84);
    tmpstruct=struct('M',transpose(M)); % Modified line to transpose windows!
    cell_array{T}=tmpstruct;
end

The code you copied is the code I am using to put my data in windows of size 85. The windows are in a structure within a cell array; I need to transpose the windows. Let me know if you need more clarification.

You missed a little ' sign inside my code that will transpose your windows. Try to run it and tell me if this is what you want.

' is not transpose; it is conjugate transpose

The OP asked this: "That is, instead of the vector of window values being 1x85, I want them to be 85x1.", and my code does -exactly- what he asks for.

@TommasoBelluzzo my code does -exactly- what he asks for except if a is complex (I assume a = 1:n in OP's code is just an example). To just transpose, use .'
