How can i solve this problem 'sawtooth' for input arguments of type 'double'?

T=5*pi; A=1; x=-T:0.1:T; y=A*sin(x/3); y1=sawtooth(x,0.5); z=y<y1; ylim([-1.5,1.5]) subplot(1,2,1); plot(x,y); hold on; plot(x,y1); hold on; zlim([-1.5,1.5]) subplot(1,2,2); plot(x,z); hold on

Marti, the code looks fine. What happens if you execute a

 clear

and then run your code again? Is this code part of a script or function or do you run it stand-alone in the command window?

I run it stand-alone in the command window my thanks in advance for your help

sawtooth is part of the Signal Processing Toolbox, which you might not have installed and/or licensed. To check, try

 which sawtooth

which should return something like

 C:\Program Files\MATLAB\R2015a\toolbox\signal\signal\sawtooth.m

or

 ver

which lists all of the installed toolboxes.
