Everything was working fine and then I tried to use persistence to allow my legend to be incremented.
It didn't work so I left it but now legend throws up an error: e.g.
x = -pi:pi/20:pi;
y1 = sin(x);
y2 = cos(x);
figure
plot(x,y1,'-ro',x,y2,'-.b')
legend('sin(x)','cos(x)')
Attempt to execute SCRIPT legend as a function:
C:\Users\sean\Desktop\matlab\legend.m
Error in simplegraph (line 7)
legend('sin(x)','cos(x)')
I tried rebooting the PC with no joy, (Matlab 2015a).
It like I have messed up matlab!
Anyone have any ideas?

Oops! I had a script called legend, I don't recall creating it, anyway deleting fixed the issue.
