MATLAB: How to concatenate two or more cell arrays into one

cellsconcatenation

I have two cells:

a =

Columns 1 through 6
    [13x1 double]    [394x1 double]    [181536.00]    [44x1 double]    [14x1 double]    [28x1 double]

b =

    []    [14x1 double]    []    [4x1 double]    []    [2x1 double]

I want one cell:

c =

Columns 1 through 6
    [13x1 double]    [408x1 double]    [181536.00]    [48x1 double]    [14x1 double]    [30x1 double]

i.e. c is the concatenation of a and b.

How?

Probably the easiest way is to use the heterogeneous version of the cat function.

It's pretty easy really. Here an example:

A = {rand([2 1]),rand([5 1]),rand([3 1])};
B = {rand([10 1]),rand([12 1])};
C = [A B]; %adds cell B to A

Try something like this:

baz = @(c) horzcat(c{:});
foo = @(x) cellfun(baz, num2cell([x.A;x.C;x.E],1), 'uni',0);
arrayfun(foo, structure, 'uni',false)
