Small Problem with 'if' statement and array index

Hello
I have a rather simple problem that I can not overcome. The problem I am facing is that I have an 'if' statement that I want to be executed only for one line of a matrix array (cell array).
I tried something like this, but doesn't work
if Seg_Out_1{1,:}==true .....
This one gives me an error 'Too many Input Arguments'. Is this the right approach, or should I do something complete different ???
Thank you in advance very much !

if isequal(Seg_Out_1(1,:),otherCellArray)

This is a matrix as the first element of a cell array?
If so (and if by line you mean row), then you want to address that by Seg_out{1}(1,:)
Seg_out = cell(2,1);
Seg_out{1} = ones(2,2);
if (Seg_out{1}(1,:) == [1 1])
% or isequal(Seg_out{1}(1,:),[1 1])
disp('true');
else
disp('false');
end

Maybe I asked the question wrongly, let me be more precise.
I have a cell array containing image arrays in every one of its locations.
I want to give specific name to every image. All the images within the same row should have the same name (almost). So I am trying to create 'if' statements for accessing every row.
A small example of my non-working code
if Seg_Out_1{1,:}==true;
% Changing name of the exporting image tif file
Exp_Name_1 ='Seg_%d_Img-Diffused_%d_%d_%d_%d_%d_%d_%d_%d_%d_%d_%d.tif';
% Export Image command
imwrite(Seg_Out_1{1,Num_Seg},[ImageExpDir,sprintf(Exp_Name_1,Num_Seg,a,b,c,d,e,f,g,h,i,j,k)],'tif');
end
if Seg_Out_1{2,:}==true;
Exp_Name_2 ='Seg_%d_Img-Edgefunction_%d_%d_%d_%d_%d_%d_%d_%d_%d_%d_%d.tif';
% Export Image command
imwrite(Seg_Out_1{2,Num_Seg},[ImageExpDir,sprintf(Exp_Name_2,Num_Seg,a,b,c,d,e,f,g,h,i,j,k)],'tif');
end

I found a way to do it !
if isequal(Seg_Out_1{1,Num_Seg},Seg_Out_1{1,Num_Seg});
...
...
...
...
...
end
if isequal(Seg_Out_1{2,Num_Seg},Seg_Out_1{2,Num_Seg});
...
...
...
...
end
