Numerical Integration using Trapezoidal & Simpson's rule (1/3 and 3/8) in SCILAB

[@hopes_alive-100]

Thank You so much, please kindly keep uploading videos of scilab !! Your way of explaination is really good. Try to cover as much part of scilab lab as possible,PLEASE !

sir, thank you for making it
but unfotunately i have some doubt
i think there is some problem in terms of your y terms taking
simpson's 1/3 formula = h/3((1st term+last term)+4*(odd terms)+2*(even terms))
simpson's 3/8 rule = 3h/8((1st term+last term)+3*(remaining terms)+2*(multiple of 3's terms))

Thanks brother

Please give us, correct practical for solving Schroedinger equation, by finite difference method.
What, you have given is wrong program, In one of your video.
Also cover other quantum mechanics, bsc du, practicals.

Which program is incorrect ? Kindly tell so that it can be rectified

This program is incorrect.

[@practicalhope5408]

And what is the error

[@shashankphysicsmaths7108]

@@practicalhope5408 my teacher said me, " you have plotted u(r).
Plot psi = u(r)/r
It is real graph of psi. And graph should be only positive, for psi vs r.
Beside it, check normalisation of psi, before plotting it."
This is the statement of my mam. Well, the biggest error she said is we are getting negative values of psi in graph.
All psi values in graph of psi vs r, must be positive.
