MATLAB: How to alter the dimensions of a cell array

cell array

Hi, I am trying to alter the dimensions of my array so it meets the requirements for training of a neural network. At the moment, the variable 'Signals_v' is a 42 x 1 cell array with the following components. Each double represents a separate array with the dimesions n x 900, 42 of which I have concatenated to create 'Signals_v'. How do I change these dimensions to effectively split up each of those doubles so that the dimensions of the cell array are instead 2243 x 1 with 1×900 doubles? Any suggestions would be greatly appreciated, thanks in advance.
    { 74×900 double}
    { 66×900 double}
    { 65×900 double}
    {101×900 double}
    { 77×900 double}
    { 56×900 double}
    { 93×900 double}
    { 65×900 double}
    { 75×900 double}
    { 67×900 double}
    { 84×900 double}
    { 98×900 double}
    { 57×900 double}
    { 55×900 double}
    { 54×900 double}
    { 61×900 double}
    { 76×900 double}
    { 79×900 double}
    { 77×900 double}
    { 85×900 double}
    { 59×900 double}
    { 76×900 double}
    { 60×900 double}
    { 53×900 double}
    { 75×900 double}
    { 50×900 double}
    { 76×900 double}
    { 11×900 double}
    { 19×900 double}
    { 14×900 double}
    { 11×900 double}
    { 31×900 double}
    { 11×900 double}
    {  8×900 double}
    {  8×900 double}
    { 13×900 double}
    { 52×900 double}
    {  4×900 double}
    { 76×900 double}
    { 35×900 double}
    { 30×900 double}
    {  6×900 double}
How do I change these dimensions such that the cell array instead contains {1 x 900} doubles?

 Signals_v=num2cell(cell2mat(Signals_v),2);
