how to cell array all data into a matrices

suppose i have a cell array

 a={{1,2,3};12;{21,32,43}};

how to get all data in single matrix

 b=[1,2,3,12,21,32,43]'

Use horzcat and cell2mat:

b = cell2mat(horzcat(a{:}))

produces:

b =

       1     2     3    12    21    32    43

I didn’t initially see the transpose operator. To get it as a column vector, add the transpose:

b = cell2mat(horzcat(a{:}))'

star ur genius

A =

    [1x4 double]    [19]    [1x4 double]    [1x4 double]

 A{:}

ans =

     1     2    14    16

ans =

    19

ans =

     6    12    15    20

ans =

     3     4     7    17

how to get it into single matrix

 B=[1,2,14,16,19,6,12,15,20,3,4,7,17]

I wish! Thank you for the compliment.

Slightly different with ‘A’ here, since it is a cell array of vectors and not a cell array of cells, so we do not need cell2mat this time:

B = horzcat(A{:})

produces:

B =

       1     2    14    16    19     6    12    15    20     3     4     7    17
