Web我不是Eigen方面的Maven，但听起来rArr.data()返回一个指针，该指针可能以某种方式转换为非零值。 此外，1/(nx*ny*nz)似乎是“整数除法”，总是返回零。 也许这是一个工作机 … Web这些函数都接受两个 Complex 类型的参数，并返回一个 Complex 类型的结果。 这样，我们就可以通过调用这些函数来实现复数的基本运算了。 customizing the pagination view

WebApr 11, 2024 · I have a code that takes the 3D FFT of an Eigen tensor and returns an Eigen tensor output. I am using a c++ array to pass it to the FFTW plan however I am having an issue getting the correct output (i.e. the size is off). Is there a better way to copy the content of the ''output_array'' into an Eigen tensor using Eigen::map instead of a for loop? WebNote: in C++, just as with ordinary malloc, you must typecast the output of fftw_malloc to whatever pointer type you are allocating. We also provide the following two convenience functions to allocate real and complex arrays with n elements, which are equivalent to (double *) fftw_malloc(sizeof(double) * n) and (fftw_complex *) fftw_malloc ...
