if condition on cell array

I have 2 cell arrays

A= n01944390

n01984695

n02056570

n02058221

n02099601

n02099712

B = n15296258 octave

n15296354 then

n15296489 shiva, shivah, shibah

n15296687 epoch, date of reference

n15296920 clotting time

n15297069 rotational latency, latency

n15297303 probation

n15297472 probation

n15297672 processing time

n15297859 air alert

I need to compare the first column if these 2 cell arrays and if they are equivalent, add the row of the matrix B to the equivalent row of matrix A

I wrote this for loop

for i=1:length(A)

    if A(i) == B (i,1)

        A(i,2) = B(i,2);

        A(i,3) = B (i,3);

    end

end

but it gives me this error message "Undefined function 'eq' for input arguments of type 'cell'."

Can anyone help me?

The notation in your question is incomprehensible. Please use valid matlab syntax (and the {} Code button to format text as code).

Anyway, if I understood correctly what you want:

[isfound, whichBrow] = ismember(A(:, 1), B(:, 1));  %find which keys of A are in the keys of B
newA = [A, cell(size(A, 1), size(B, 2)-1)];         %add columns to A to receive the columns of B
newA(isfound, 2:end) = B(whichBrow(isfound), 2:end) %and copy columns that matched
