Hi all

As the title above, suppose i have matrix A like:

A={[12;13] ;[1,5] ;[5;6;7]; [1,3,5,4]};

i want the matrix A have vertical or horizontal array, look like:

A = 12 13 1 5 5 6 7 1 3 5 4
or
A =
    12
    13
     1
     5
     5
     6
     7
     1
     3
     5
     4

i know for produce horizontal array using:

[[12;13]' [1,5] [5;6;7]' [1,3,5,4]]

and for vertical array using:

[[12;13] ;[1,5]' ;[5;6;7]; [1,3,5,4]']

but note for this situation i work with big and long array, where has the number ; and , various.

I really appreciate the help. tks

A={[12;13] ;[1,5] ;[5;6;7]; [1,3,5,4]};
% make each element of A a row vector

A = 4×1 cell array
    {[  12 13]}
    {[    1 5]}
    {[  5 6 7]}
    {[1 3 5 4]}
% horizontally concatenate all elements of A
A = [A{:}]
A = 1×11

% or ...
