    MATLAB Fortran 90 vs Matlab: Comparing Program Speed

    Thanks for the answer minger. I have tried those changes, and althought they sightly improve the speed, it is still a lot slower than matlab. The code in fortran now looks like this: program D2D IMPLICIT NONE integer, parameter::NxL=11 integer, parameter::NyL=9 integer...

    MATLAB Fortran 90 vs Matlab: Comparing Program Speed

    Hello. I am trying to translate a program written in MATLAB to a fortran code and I have found out that the fortran code is slower. I couldn't believe it so I decided to do a simple program in fortran 90 and MATLAB in order to be sure. The code in MATLAB is: function D2D() Nx=2^11...

    How to predic the possible values of Lx

    Hello, I would like to ask you something about angular momentum in quantum mechanics; If I know that when t=0, my wave function is \Psi=\Upsilon^{m}_{l} and l=3 and m=0, How can I calculate the probability of getting the value \hbar meassuring L_{x}?

    Schrodinger Equation for a central 2D potential

    Hello, I would like to ask something about central potentials. When I am working in 3D, I haven´t got any problem solving the schrodinger equation since I use the following change of variables: -\frac{\hbar^{2}}{2m}\nabla^{2}\Psi+V(r)\Psi=E\Psi \Psi=\frac{\chi}{r} With this change of...

    What are some tips for getting accepted into summer programs for physics?

    Thanks for your answer Choppy. Yes, You understand wright, I am an undergraduate student, and my career has 5 courses (meant to be studied in 5 years) but I have completed 4 courses in only two years. Maybe the reason why I am being rejected is that my experience as an undergraduate student...

    What are some tips for getting accepted into summer programs for physics?

    Hello, I would like to ask you some questions relating summer programs in physics. I have applied for several programs this year and one by one, I am being rejected in all of them. I don't know why this happens, my marks are really good, and I have studied four courses of the physical sciences...

    Differential equation what going on?

    Hey James dx/dt= xt dx/x = t·dt Ln(x) = (t^2)/2 + K x=e t2 /2 +K = e K · e t2 /2 If we say that e^K = C then; x= C·e t2 /2 I hope it helps

    Physics Is it too late to pursue a PhD in physics at 29?

    Too old being 29? Where I live, people start their career at 18, then they spend 5 years studying it, so they start their Ph.D. when they are 22. If you spend 6 years doing a Ph.D. then you will finish when you are 28! So, to sum up, I think 29 is a normal age!
