However, I found another thread that partially answers this: MATLAB-style find() function in Python John posted the following code that accounts for the first argument of find, in your case A>9 ---find(A>9,1)-- but not the second argument. I altered John's code which I believe accou...
delta = v.*sign′(x).*max(abs(x),TypicalX), 当 sign′(x) = sign(x) except sign′(0) = 1 中心有限差分为 delta = v.*max(abs(x),TypicalX) 标量FiniteDifferenceStepSize扩展为矢量。前向有限差的默认值为sqrt(eps),中心有限差分的默认值为eps^(1/3)。

the details of the training rather than the broad patterns. A common sign of overfitting is that your model performs well on the training set but not on new data. You can use afeature selectiontechnique to find and remove features that do not significantly add to the performance of your ...

Now, I found a good candidate in the scipy signal find_peaks function (https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.find_peaks.html). This seems very similar. But as is, it does not provide the results I want. In fact it returns the peaks and a dictionary containin...
