自定义FFT卷积使用fftshift(fft(fftshift(signal))): 1.不改变频谱的幅度和相位 2.使得频谱的范围为-Fs/2到Fs/2，中心频率为0 1234567891011121314def fftconvolve(im, gauss_kernel): gauss_f = np.fft.fftshift(np.fft.fft2(np.fft.fft

问题给你一个由数字和运算符组成的字符串 expression ，按不同优先级组合数字和运算符，计算并返回所有可能组合的结果。你可以 按任意顺序 返回答案。 生成的测试用例满足其对应输出值符合 32 位整数范围，不同结果的数量不超过 $10^4$ 。 示例12345输入：expression = "2-1-1"输出：[0,2]解释：((2-1)-1) = 0 (2-(1-1))

PRL投稿问题PRL投稿需要使用REVTEX，而使用REVTEX模板发现去除所有内容后，abstract后自动换页然后输出。

We recommend using Static Generation (with and without data) whenever possible because your page can be built once and served by CDN, which makes it much faster than having a server render the page on

Next.js has two forms of pre-rendering: Static Generation and Server-side Rendering. The difference is in when it generates the HTML for a page. Static Generation is the pre-rendering method that gen
