I have been trying to graph a triangular wave,sawtooth function on math lab r2015a i have been the example code from their website

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

plot(t,x);

but it dose3nt run...

i tried to make my own code to graph a regular line mx+b and get the absolute value of the function to let it repeat over all the t values and make the same result and limit the max value to 1

t = linspace(-2,2,1e4); % time vector [s] x = zeros(size(t)); % this creates a vector of zeros the same size % as the vector t x(mod(abs(t),2) < 1 | mod(abs(t),2) > 0 ) = 1;

tmin = min(t); tmax = max(t); xmin = -0.2; xmax = 1.2; plot(t,x); axis([tmin tmax xmin xmax]);

this is just graphing a regular line all...

i know im doing some lame mistake and thats why the code is not running in either cases... ill appreciate any type of help to make this run... thank you
