some matlab functions like sawtooth, square etc are not running and display error in command window of "signal processing toolbox" ... any possible solution???

T=10*(1/50);
fa=1000;
dt=1/fa;
t=0:dt:T-dt;
x=sawtooth(2*pi*50*t);
plot(t,x);

Please ost the complete error message.

It seems that you don't have access to the Signal Processing Toolbox, which contain the sawtooth and square functions.

You need to have access to a Particular Toolbox to access the functions of the toolbox.

How to obtain a toolbox?

- By purchasing it.

- If you are a college student, your college might have a campus-wide license to MATLAB, with access to toolboxes. Contact your college authority dealing with such issues.

A third solution is to implement the function yourself. This may require a considerable effort.

Hi Moiz,

I understand that you are trying to plot a 'Sawtooth function' programmatically in MATLAB with given specifications.

To do this, make ensure that ‘Signal Processing toolbox’ is installed in you packages or you can install it from MATLAB add-ons as well .Also ,you may try running it on MATLAB online as it has necessary features preinstalled in it.

I tried reproducing it on my machine Refer to the below code snippet and output of that for better understanding.

T=10*(1/50); 

fa=1000; 

dt=1/fa; 

t=0:dt:T-dt; 

x=sawtooth(2*pi*50*t); 

plot(t,x); 

Refer to the below documentation for details : Link
