Index exceeds matrix dimensions

I have a file that plots results from a simulation. Ive been using it for a long time and now it has started giving me this problem:

Index exceeds matrix dimensions.

Error in Plot_Results (line 210)
    title('Velocity of cycle')

The first time I run the file it works fine. But if I run it again without changing anything (and there is nothing to clear any variables in the code) it gives me that error. If I comment out every title, xlabel, and ylabel line then itll work fine and will plot the several plots I have in the file but with no titles or anything. This just started happening and I cant figure out why. The code was working just fine before this randomly started happening.

thanks

Alright I figured it out. For some reason it wasnt rewriting the title variable from an old run so i just added "clear title xlabel ylabel" and that seems to have fixed it.

I just found that I accidentally used the name "title" for a string, which confused Matlab. Try use another name.

I had made xlabel and ylabel a variable which gave me the error about index exceeds array.

xlabel = ('time')
ylabel = ('something')

all I had to do was clear these variables

>>clear xlabel
>>clear ylabel

and use the proper syntax

xlabel('time')
ylabel('something')

[Haseeb Ahmed Janjua]

whenever I create this function in editor

function r = Ymaxfinal(p,q)

r = ((-1000*p*q)/(27*(30*10^6)*0.163*(p+q)))*(p+(2*q))*((3*p(p+(2*q)))^0.5);

end

but when I call it in command window like Ymaxfinal(9,8)

it gives the error of Index exceeds matrix dimensions. plz help me
