Change your working directory name to something other than standard matlab installed folders

[Walter Roberson]

sawtooth() is part of the Signal Processing Toolbox

[shivam Kumar]

please give solution

[Walter Roberson]

sawtooth was supported in R2015a.

I do not have the link for the R2015a documentation, but the R2015b documentation link is https://www.mathworks.com/help/releases/R2015b/signal/ref/sawtooth.html

and the function is marked as existing before R2006a.

You do, however, need to have the Communications Systems Toolbox installed and licensed in order to use it.
