在Python中,所有数据类型都可以视为对象,当然也可以自定义对象。自定义的对象数据类型就是面向对象中的类(Class)的概念。 我们以一个例子来说明面向过程和面向对象在程序流程上的不同之处。假设我们要处理学生的成绩表,为了表示一个学生的成绩,面向过程的程序可以用一个dict表示: ''' std1 = {"name":"Michael"...

The computational efficiency of the FFT means that it can also be a faster way to compute large convolutions, using the property that a convolution in the time domain is equivalent to a point-by-point multiplication in the frequency domain....

由于本软件的支持库是以git submodule形式引入的, 所以请在克隆仓库时, 使用git clone --recursive命令递归将子模块一起克隆下来, 如果克隆时忘记, 也可以在克隆完成之后在源码路径下执行git submodule init和git submodule update两条指令来补救 如果你使用Download ZIP功能而不是git clone, 那么请将z-fft一同下载,...
zfft= dsp.ZoomFFT(Name,Value)creates a zoom FFT object with each specified property set to the specified value. Enclose each property name in single quotes. You can use this syntax with any previous input argument combinations. Example:zfft = dsp.ZoomFFT(2,2e3,48e3,'FFTLength',64); ...
R2014a and earlier report 'FreeMemory' as a property of gpuDevice. This just tells you how much memory on the device isn't assigned to MATLAB. In R2014b we changed this to 'AvailableMemory', this tells you how much space there is on device plus how much...
The severity and number of overflow exceptions in a block depends on the scaling scheme used and the property of the input data. If the user is using an appropriate scaling method for the expected input data and can tolerate occasional exceptions, the except output may be left unconnected ...
