contains i (iota ) in denominator. It's python equivalent line would be: V_modif[j -1] = Y_modif[j -1,:] / ( 1j*2* np.pi * f) but this gives zero in ouput and if you remove "1j" from denominator it gives corrcet output but contains ...

Correlation matrix – How to use .corr() The easiest way to check the correlation between variables is to use the.corr()method. data.corr()will give us the correlation matrix for the dataset. Here is a small sample from the big table: Note: If you want to learn in detail, how to r...

Likewise it is also possible having events that are causally dependent while observing a very small or no apparent correlation, i.e., corr(X,Y) ≈ 0, within the data sampled. Such a situation could make us conclude wrongly that they have nothing to do with each other. Correlation is a ...
