MATLAB: Concatenate a column of cells into a single array

cell arrayconcatenateMATLAB

Hello,

I have a cell containing multiple arrays that I want to concatenate into a single array such that X{1}, X{2},… are all each a 100×1 double. I am hoping for a non looping solution that will put them all together into a single array that is 100xlength(X). I have tried using cat(), vertcat() and others but keep getting the error that 'dimensions of arrays being concatenated are not consistent.' Any help is greatly appreciated, thanks!

cell2mat(X)

mat2cell

is usefulll for other purpose

b = mat2cell(a.',[1 1 1 1])

b =

1×4 cell array

{4×1 double} {4×1 double} {4×1 double} {4×1 double}

MATLAB: Accessing cell array data every 2 columns and concatenating them

Easy with cellfun:

%generate random data:
A=cell(3,6);x=[137 134 410 411 439 455];
for r=1:size(A,1)
    for c=1:size(A,2)
        A{r,c}=num2cell(randi(10,1,x(c)));
    end
end
%the actual line of code:
A=cellfun(@(x1,x2) [x1,x2],A(:,1:2:end),A(:,2:2:end),'UniformOutput',0);
