Verification of loaded and copied data

I have Data points, one using the load function and another just copied. How can I verify the tolerance between is within an acceptable range using an if > array comp > else loop??

DATA

The 1st,15th and last rows of the copied data are:

0.0000 -0.2086

1.7500 0.0443

5.0000 2.2534

The 1st,15th and last rows of the loaded data are:

0.0000 -0.2086

1.7500 0.0443

5.0000 2.2534

Not sure what you want but try subtracting and looking at absolute value of the difference

diffMatrix = abs(m1 - m2); % Difference of your two matrices.
tolerance = 0.01; % Whatever.
if any(diffMatrix(:) > tolerance)
    maxDiff = max(diffMatrix(:))
    warningMessage = sprintf('Warning : some elements differ by more than %f (up to %f).', ...
        tolerance, maxDiff);
    uiwait(warndlg(warningMessage));
end

Adapt as needed.
