create cell array by extracting all the same row from multiple matrix
显示 更早的评论
I have three double A = [105x3]; B = [105x3]; C = [105x3]; I want to create a cell array D = {105 cells} each cells contains the corresponding rows from A B C.
For example,
D {1} = [
A(1,:);
B(1,:);
C(1,:);]
each row from A B C are in different rows in D
Is this achievable through cellfun?

"Is this achievable through cellfun?"
Yes:
A = rand(105,3);
B = rand(105,3);
C = rand(105,3);
D = cellfun(@vertcat,num2cell(A,2),num2cell(B,2),num2cell(C,2), 'uni',0)
But most likely you should be using ND arrays rather than concatenating & splitting data like that.

"But I am not sure I understand the 'using ND arrays' in your suggestion."

D = cell(105,5) ;
for i = 1:105
D{i} = [A(i,:) B(i,:) C(i,:)] ;
end
Or
D = [A B C] ;
D = num2cell(D,2) ;
