Hello everyone, and thanks in advance
let's say I have a cell of 10 arrays. but the arrays are not having the same dimensions.
example: 60000x1 , 65478x1, 74578x1 and so on. how can i make all the arrays the same size, knowing that i want the dimensions to have the least size so no zeros padding.
thanks a lot

minlen = min(cellfun(@length, YourCell));
truncCell = cellfun(@(C) C(1:minlen), YourCell, 'uniform', 0)

% demo data
C{1} = rand(60000,1) ;
C{2} = rand(65478,1) ;
C{3} = rand(74578,1) ;
% lengths of each cell array
L = cellfun(@length,C) ;
% do interpolation to get the cell array to same size
for i = 1:length(C)
C{i} = interp1((1:L(i))',C{i},linspace(1,L(i),min(L))) ;
end

i have 10 cells and sometimes more, is there any dynamic way to accept any number of arrays and reduce them to the smallest matrix size?

The above code works for any given cell array C of any size .
