How do I convert a 3d cell array of different size to matrix?

How can we convert a 3d cell array to matrice. can I get 1x10 matrices from the 1x10 cell?

M = cat(3, ETT{:});

No, this cannot create a 1x10 matrix.

Thanks Jan for the answer. Now i am getting a matrix of 1x31x2193. Can reshape to 10 matrices of sizes as shown in below figure?

But you had 10 such matrices initially stored in the cell array. I do not see the reason to join the data only to split them again. Using Ett{1} to Ett{10} is the best strategy to handle 10 matrices of different size.

Each time the number of matrices will change. Here it is 10. sometimes it will be 20 or 50 number of matrices. Any way to automate such that i will get the number of matrices as per the number of cell arrays!

Here since 10 number of matrices are there, Ett{1} to Ett{10} is the best strategy but when when large number of matrices are there, then it will be cumbersome...

If you have 10 million matrices, using a cell array and an index is still the best solution. Most of all, you do not have to hardcode the names of the variables at all, so using this method is flexible by design.

Thank you for a great discussion!
