Summing matrices of cell arrays

So i have three cell class variables size of 101x5. I need to combine the three of them to form only one cell array of size 101X5. I have tried concatinating the matrices before summing them and I get an error saying "Undefined function 'sum' for input arguments of type 'cell'."How can I get around this?

Answer 1

[Walter Roberson]

num2cell( sum( cat(3,cell2mat(V1), cell2mat(V2), cell2mat(V3)), 3) )

This depends upon the individual cells holding scalars. If they do not then

cellfun(@(A,B,C) A+B+C, V1, V2, V3, 'Uniform', 0)

Thanks ! Mr. Roberson

However, I still get:

Error using cell2mat (line 53)

Cannot support cell arrays containing cell arrays or objects.

[num,data] = xlsread('Connection_List.xlsx','A:E');

[str1] = regexp(data,'304W00','match','ignorecase');

[str2] = regexp(data,'DBC[A-Z]','match','ignorecase');

[str3] = regexp(data,'P01_[A-Z]','match','ignorecase');

this is part of my code....what i want to do is sum str1+str2+str3 where each contains cell arrays 101 X 5

You want to sum strings?? What does that mean?

Do you want to sum or do you want to concatenate?

[Diego Tasso]

I do not want to sum strings....they are just the name the previous coding person used....its just a variable name. I want to sum the cell arrays. I tried concatinating the cells before summing them in another dimension as you suggested above but I got the error I commented previously about cell2mat not supporting cell arrays containig cell arrays. Should I not concatinate before summing?

I was tring to sum cell arrays of strings.
