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]
strider plz check

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
