cell2mat(cell2mat(a))

does not work

Answer 1

[madhan ravi]

>> a=rand(1,20);
   a=num2cell(a)
   c=(cell2mat(a)) 

a =

    1×20 cell array

    Columns 1 through 5

      {[0.5238]}    {[0.5338]}    {[0.8043]}    {[0.0651]}    {[0.5096]}

    Columns 6 through 10

      {[0.7079]}    {[0.4156]}    {[0.9226]}    {[0.0987]}    {[0.6105]}

    Columns 11 through 15

      {[0.7985]}    {[0.2011]}    {[0.3426]}    {[0.2271]}    {[0.7768]}

    Columns 16 through 20

      {[0.2135]}    {[0.6125]}    {[0.9852]}    {[0.2758]}    {[0.7852]}

c =

    Columns 1 through 7

      0.5238    0.5338    0.8043    0.0651    0.5096    0.7079    0.4156

    Columns 8 through 14

      0.9226    0.0987    0.6105    0.7985    0.2011    0.3426    0.2271

    Columns 15 through 20

      0.7768    0.2135    0.6125    0.9852    0.2758    0.7852

Thanks @Ravi I got the answer

x = cell2mat(table2array(cell2table((x))));

[madhan ravi]

glad that you found

Let A - your cell array with cells

out = cell2mat(cellfun(@cell2mat,A,'un',0));

Answer 3

[Bruno Luong]

Just cascading CAT as many as nested level

>> c={{[1 2]} {[3 4 5]}}

c =

    1×2 cell array

      {1×1 cell}    {1×1 cell}

>> c1=cat(2,c{:})

c1 =

    1×2 cell array

      {1×2 double}    {1×3 double}

>> a= cat(2,c1{:})

a =

       1     2     3     4     5

>>

Or doing in loop

a = c; 
for level=1:2
   a = cat(2,a{:});
end
