I am working on a project that needs vector math and complex numbers开发者_如何学编程. I am looking a for a good open source API that supports C/C++ and hopefully has decent performance.
I\'m using right now the scipy.integrate.quad to successfu开发者_Go百科lly integrate some real integrands. Now a situation appeared that I need to integrate a complex integrand. quad seems not be able
Is it possible to store negative zero in imaginary part of C99 complex float? How I should statically initialize complex constants with signed imaginary part?
Given a std::vector of std::complex, I would like to transform it to a vector containing only the real part of the complex, divided by some constant coefficient.
I\'m trying to implement a discrete fourier transform, but it\'s not working. I\'m prob开发者_JS百科ably have written a bug somewhere, but I haven\'t found it yet.
I have a stream of incoming data that has interleaved real and imaginary integers. Converting these to complex64 values is the slowest operation in my program. This is my current approach:
How can I make a Mathematica graphics that copies the behaviour of complex_plot in sage? i.e. ... takes a complex function of one
I am trying to find the fourier transform of an image in matlab. I am doing this without the hep of the library function. The code is:
may you tell me how to write a complex variable in C++ code please? I do have separate real part psi_rl and imaginary part psi_im. Now I have to write psi = psi_rl + i psi_im. Do you have any idea ho
I\'m doing an assignment for a CSE class in Java and am implementing a FFT and the direct DFT (with matrix calculations). My FFT works fine, but my direct DFT is not working. My Fourier matrix is not
