Insert/Concatenate cell array into nested cell array (by column and repeat in each row)

I have CA a 1x3 cell array with {3x13 cell} {3x11 cell} {3x11 cell}. Each nested cell have 2x# double arrays.

Example CA{1} =

3×13 cell array

Columns 1 through 7

[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]

[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]

[2×153 double] [2×154 double] [2×156 double] [2×154 double] [2×156 double] [2×155 double] [2×154 double]

Columns 8 through 13

[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]

[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]

[2×151 double] [2×152 double] [2×152 double] [2×154 double] [2×154 double] [2×161 double]

I also have 3 individual cell arrays A {1x13 cell}, B {1x11 cell}, C{1x11 cell}. Each cell have 3x# double arrays.

Example A =

1×13 cell array

Columns 1 through 7

[3×153 double] [3×154 double] [3×156 double] [3×154 double] [3×156 double] [3×155 double] [3×154 double]

Columns 8 through 13

[3×151 double] [3×152 double] [3×152 double] [3×154 double] [3×154 double] [3×161 double]

I need to add/insert/concatenate A into each row of CA{1} to create:

CA_5{1} =

Columns 1 through 7

[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]

[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]

[5×153 double] [5×154 double] [5×156 double] [5×154 double] [5×156 double] [5×155 double] [5×154 double]

Columns 8 through 13

[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]

[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]

[5×151 double] [5×152 double] [5×154 double] [5×154 double] [5×161 double]

B corresponds to CA{2} and C to CA{3}.

I tried to use cellfun and arrayfun but I cannot get to re-concatenate into each row.

cellfun(@(x,y) [x;y], CA{1}, A,'uni',1);

Thanks

Thanks! It worked.

Change 'uniformoutput' to 0

CA{1}=cell(1,13);
A=cell(1,13);
for k=1:13
    r=randi([2 4]);
    %random data to show concatenation
    A{k}=rand(r,156-k);
    CA{1}{k}=rand(r,156-k);
end
CA{1}

ans = 1×13 cell array
    {3×155 double}    {4×154 double}    {2×153 double}    {4×152 double}    {2×151 double}    {3×150 double}    {3×149 double}    {3×148 double}    {4×147 double}    {2×146 double}    {4×145 double}    {3×144 double}    {2×143 double}

A

A = 1×13 cell array
    {3×155 double}    {4×154 double}    {2×153 double}    {4×152 double}    {2×151 double}    {3×150 double}    {3×149 double}    {3×148 double}    {4×147 double}    {2×146 double}    {4×145 double}    {3×144 double}    {2×143 double}

%assign it accordingly
out{1} = cellfun(@(x,y) [x;y], CA{1}, A, 'uni', 0);
out{1}

ans = 1×13 cell array
    {6×155 double}    {8×154 double}    {4×153 double}    {8×152 double}    {4×151 double}    {6×150 double}    {6×149 double}    {6×148 double}    {8×147 double}    {4×146 double}    {8×145 double}    {6×144 double}    {4×143 double}

%similarly for B and C as well

[ErikaZ]

It doesn't work. I get the error:

Error using cellfun
All of the input arguments must be of the same size and shape.
Previous inputs had size 3 in dimension 1. Input #3 has size 1 

It is because in your example yourCA{1} is {1x13}. And mine CA{1} is {3x13} and A is {1x13}.

I need to concatetane A to each row of CA{1}.

Could you please attach your data via the paperclip button?

[ErikaZ]

Done. I added it to the main question.
