I have a bunch of variables, and my program checks to make sure they are equal:
if strcmp(TrueValMat{2,1}, BOX(1,:))...
&& strcmp(TrueValMat{2,2}, BOX(2,:))...
&& strcmp(TrueValMat{2,3}, BOX(3,:))...
&& strcmp(TrueValMat{2,4}, BOX(4,:))...
&& strcmp(TrueValMat{2,5}, BOX(5,:))...
&& strcmp(TrueValMat{2,6}, BOX(6,:))...
&& strcmp(TrueValMat{2,7}, BOX(7,:))...
&& strcmp(TrueValMat{2,8}, BOX(8,:))
set(handles.certifyButton, 'enable', 'on');
end
I know it is ugly, but it works. It indexes cells from an excel file (TrueValMat), and compares each cell to a value in an array (BOX). if they all match, a button is enabled in a GUI.
I want it to do the opposite. I want this to compare the cells from TrueValMat and BOX, and if any of them are found to be unequal, then the condition will be met, and the GUI button will be enabled. I don't care if only a single pair doesn't match, or all of them don't match. as soon as there is a logical 0 found, it trips the condition.
How would I do this?

if ~( strcmp(TrueValMat{2,1}, BOX(1,:))...
&& strcmp(TrueValMat{2,2}, BOX(2,:))...
&& strcmp(TrueValMat{2,3}, BOX(3,:))...
&& strcmp(TrueValMat{2,4}, BOX(4,:))...
&& strcmp(TrueValMat{2,5}, BOX(5,:))...
&& strcmp(TrueValMat{2,6}, BOX(6,:))...
&& strcmp(TrueValMat{2,7}, BOX(7,:))...
&& strcmp(TrueValMat{2,8}, BOX(8,:)) )
set(handles.certifyButton, 'enable', 'on');
end

Ok, that brings up an issue I didn't think about. If all of them match, I want the button to be disabled. According to this fix, all of them matching would be enable it as well. Any way to avoid that?

Won't this onto trigger if all are found to be false? I want the condition to be triggered even if only a single condition is found false
