Hello Guys,
I have two Matlab cells that I have one row in common. I have to merge to Add to the first the uncommon rows of the second one.
commonValue=intersect(r_ptf{12,:},r_ptf3{12,:});
Could someone help me out

When it comes to cell arrays, it's pretty-much impossible to write generic code w/o knowing the content since it could be anything.
As @Dyuman Joshi requested, for somebody to be able to help, we'll need to see a small sample case that illustrates what the content of the two cell arrays is...it doesn't need (and shouldn't be) huge; just make up a test case that illustrates wht your situation is...only 10 or so rows and columns would be more than enough; but it needs to be representative of the real thing.

Hi,
Here are the steps and the code you could refer:
% Find the common value
commonValue = intersect(r_ptf{12,:}, r_ptf3{12,:});
% Find the indices of the rows that have the common value in both cells
idx1 = find(ismember(r_ptf{12,:}, commonValue));
idx2 = find(ismember(r_ptf3{12,:}, commonValue));
% Remove the rows with the common value from the second cell
r_ptf3(idx2,:) = [];
% Merge the two cells by adding the uncommon rows of the second cell to the first cell
r_ptf = [r_ptf; r_ptf3];
Refer to the following documentation for ismember:
Array elements that are members of set array - MATLAB ismember (mathworks.com)
