1. matlab 中simulink 里的sine wave 模块可以是连续的也可以是离散的 2.当将Sample time参数设置成0时，它就是连续的模型，设置成大于零时，就是离散的模型，具体可以看help-1. matlab in simulink in the sine wave modules can be continuous or may be 2. When the Sample time parameter is set to 0, it is the continu

The Haar transform is the simplest of the wavelet transforms. This transform cross-multiplies a function against the Haar wavelet with various shifts and stretches, like the Fourier transform cross-multiplies a function against a sine wave with two p
