Thanks a lot, it was really useful.

Greetings from Spain!

Hey, if I have to create a function with 2 input arguments (vectors) and the output should be the value of the derivative, how is it written?

SALAM! My matlab says “The selected cannot be evaluated because it contain invalid statement” WHILE i have tried different techniques… even wrote as same as yours…

Hi I was wondering if you have any expertise with the “comet” function and would be able to help me sort out some code?

I have this code here:

a=(1:0.5:1000);

angle=a.*75;

x=cos(angle);

y=sin(angle);

t=0.5;

Ex=x.*Er;

Ey=y.*Er;

DELAY = 1;

%edit comet

%axis=5*10^12;

comet(Ex,Ey,0)

%axis([-axis axis -axis axis]);

And it works except for the fact that it’s too fast! I can’t get it to slow down with any pause or delay functions, any ideas?

how can i input any function i want in matlab. i mean something like (input(‘enter yout function’))

ty

thank you for this example, very helpful 🙂

than u very much

well said!

Thanks a lot.

very good!!!

Hey, How to write a function that its number of outputs depends on the value of its input…for example:

[n1,n2,………nr]=myfunction(r)

is this possible in Matlab?

Thank you so much, that was awesome explained

Great Video!

Thank you SO much! It’s 3 am and I’ve been struggling so much! You are amazing.

very very good!

An outstanding tutorial, clear and with valuable common/standard practice issues. Same for the other tutorials on your channel. A very good balance between capability and options.

Thanks so much ….
