Direct Equivalent 使用numpy的直接等价物是: >>> import numpy as np>>> yc = np.empty(182)>>> yc[:45] = -2 # Equivalent to, yc[0:45] = -2>>> yc[45:90] = 2>>> yc[90:136] = -2>>> yc[136:] = 2 # Equivalent to, yc[136:182] = 2 其中np.empty创建具有给定形状的随机...
% - Running time independent of r; % - Equivalent to the function: colfilt(imSrc, [2*r+1, 2*r+1], 'sliding', @sum); % - But much faster. [hei, wid] = size(imSrc); imDst = zeros(size(imSrc)); %cumulative sum over Y axis imCum = cumsum(imSrc, 1); %difference over ...
replacechildren — Remove all child objects, but do not reset figure properties (equivalent to clf). The newplot function provides an easy way to handle the NextPlot property. For more information, see the axes NextPlot property and Controlling Graphics Output. FRAME2IMReturn image data associated ...

equivalent to correlation performed in coherent detection. For Gaussian case Matched Filter detection is optimal because it maximizes the SNR of received signal and making it apt for detection. Matched filter allows the detection of bits which are below the threshold. But for the ...
