How do I convert a cell into numeric array?

Good Day everyone.

I have a cell array (1 x 300) which each cell contain 30 x 3 double array as illustrated below.

each of double array contain 30 x 3 data that i wanted to convert to numeric array instead of being saved in a cell array.

Previously, I did convert them manually. Is there anyone having idea how to convert with a code? I have bunch of them that takes longer time by doing it manually.

I have tried a code as below, but useless. can any experts help me on this? Much thanks!

for i = 1:300
     
     for j = 1 : 300
         
         Walk{j} = str2double(W(i));
         
     end
     
end

[W{:}] %at the end where W is your 1 by 300 cell array
%or
cell2mat(W)
%or
horzcat(W{:})
%or
vertcat(W{:})

And, of course, if all the cell contents are the same size, and you just want to end up with a 2-D array, then there was no need to create the cell array in the first place. You should have just created a regular numerical double array in the first place.
