Title causes error when trying to plot graph

For some reason my code won't put a title on the axes. I get the error:

Attempted to access title(104); index out of bounds because
numel(title)=6.

Error in DisplayShift_Fluorescence (line 41)
title('h');

plot(AverageCalibrated(1:32,9),AverageCalibrated(1:32,10))
hold on
plot(AverageNonCalibrated(1:32,9),AverageNonCalibrated(1:32,10),'r')
legend('Calibrated','NonCalibrated')
xlabel('Wavelength')
ylabel('Intensity')
title('h');

That means you have a variable named title

which title
whos title

To resolve it clear or rename that variable:

clear title

[Azzi Abdelmalek]

the function title was shadowed by the created variable title

title = 6;  % Or whatever
plot(1:10)
title('my plot') % title function is masked by title variable

Thanks for the help. I had set title as a variable earlier. Deleted it when I decided to plot, but it was of course still saved in the workspace.

Sean and Azzi, you guys are probably correct!
