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
