Did you know?
WebFrees all GPU resources associated with a cuFFT plan and destroys the internal plan data structure. This function should be called once a plan is no longer needed, to avoid wasting GPU memory. Parameters: plan[In] – The cufftHandle object of the plan to be destroyed. Return values: CUFFT_SUCCESS – cuFFT successfully destroyed the FFT plan ... Webr,j特征和双谱特征是信号处理中常用的特征,它们之间存在一定的关系。r,j特征是一种时域特征,用于描述信号的瞬时幅度和相位信息;而双谱特征是一种频域特征,用于描述信号的时变频率和频率调制信息。
