Say I try to evaluate this function with the dot notations, how would I proceed on changing this to the form desired.
f=@(t) 2*F0.*t.*(t>-0.5*T0).*(t<=0.5.*T0)+ ...
(2*F0.*t+2).*(t>-T0).*(t<=-0.5.*T0)+ ...
(2*F0.*t-2).*(t>0.5*T0).*(t<=T0);
f=@(t1) 2*F1.*t1.*(t1>-0.5*T1).*(t1<=0.5.*T1)+ ...
(2*F1.*t1+2).*(t1>-T1).*(t1<=-0.5.*T1)+ ...
(2*F1.*t1-2).*(t1>0.5*T1).*(t1<=T1);

Tbh i have no idea what dot notation is. I am trying to figure it out. But my professor says we cant use dot notation, so im trying to figure out how to read the code to then transfer.

I suspect your professor wants you to undo all the beautiful array operations, which is the reverse of what you should normally do.
How much of the basic Matlab syntax do you understand? Are you currently doing a Matlab course?

I'm not certain what sort of 'dot notation' is in question here.
The '.' - dots in your code are multiplication operators. In Matlab, there are two kinds of multiplication operators
1) * [star/asterisk]
2) .* [dot followed by star]
The former performs matrix multiplication and the latter is used for element-wise multiplications.
I hope this helps you understand your code better and clears up what the dots mean.
