    Graduate How Do Wavelets Compare to Fourier Transforms for Analyzing Non-Uniform Signals?

    Well, I am working on the Non uniform fast Fourier transform, which can be use on non uniform signal now days, and i am stuck some where...I am trying to produce the same results as from A.J.W.Duijndam and M.A.Schonewillie but i am not able to produce my time signal back anyone interested

    Undergrad Why is Fourier Integral Meaningless for f(x)=A*cos(ax)?

    I am experimenting with non uniform sampling, I applied Fast Fourier transform on the non uniform sampling in MATLAB it has given me some results. I can't understand how FFT runs on non uniform sampling. What i am getting after applying FFT on Non uniform samples is what...is it a errorfull...

    Fortran (3I3,F9.6) Fortran source code

    Few questions about Fortran 1. How can i calculate the user run time for my program , i am using fortran 90 and gfortran as compiler 2. How to draw the graph between the speed of two different programmes 3. Suppose i have a algorithm then how to calculate the complexity of algorithm...

    Undergrad Why is Fourier Integral Meaningless for f(x)=A*cos(ax)?

    well i am a computer guy :) so i don't know...ok here is my question following are two equations $fk(k1) = \frac{1}{nj} \sum_{j=1}^{nj} c_j(j) \exp (i k1 x_j(j))$\\ $where \frac {-ms}{2} <k1 < \frac{ms-1}{2}$ a) what is k1 b) what is x_j(j) c) what is c_j(j) Is this a forward...

    Fortran (3I3,F9.6) Fortran source code

    3I3 means 126,128,133 these are three integers which represent 3 and having three digit in each of them which say I3

    Fortran Calculating Orbits: Finding Satellite Distance from Earth

    What about calculating floating point operation, suppose i have a mac and i am running a program then how to compare two programs ..how to plot graphs between floating point operations ...between these two programs

    Fortran Calculating Orbits: Finding Satellite Distance from Earth

    Few questions in fortran :) 1. Which is the best plotting tool in fortran 2. How to get out put in form of .dat files in fortran 3. Can anyone post a code for calculating floating point operations and finally plotting it..I read so many papers i never able to understand how they plot those

    Learn Fortran for Atomic/Particle Physics Grad Studies

    Well, fortran is a dinosour language, but its very powerfull if you want to do High Performance computing ..and believe me fortran is a language completely based on scientific computing ..:)..and it doesnot matter what u start ...if u do fortran u can learn c++ easily...

    Physics Should I Leave Physics? Deciding Between a Career in Physics & Engineering

    Well well, I love physics..:) I had done civil engineering at my bachelors level...then i worked with computer industry as a programmer fr 2 year .. now i am in geophysics :) doing my master ...:) ...oha i really don't know where i am going
