Numpy array assignment along axis and index
I have a 3D volume and I modify slices along different axis. (np.take is equivalent of writing self.volume[idx], self.volume[:, idx] and self.volume[:, :, idx]) Finally, I want to assign a new slice in my volume along the axis : This is where I need some help. I can’t figure out a cleaner way of doing t…
Sympy – Arithmetic and geometric sequence in recursive form
I would like to define arithmetic and geometric sequences in recursive form like Un+1 = Un + r (u0 n>0) Un+1 = qUn (u0 n>0) In Sympy, one can define in closed form an arithmetic sequence like this : How can I define (not solve) this sequence in recursive form (Un+1 = Un + r) ? Answer You’ll need t…

Numpy applying a time interval sequence to a multidimensional ndarray (such as coordinates)
EDIT: added prefix / suffix value to interval arrays to make them the same length as their corresponding data arrays, as per @user1319128 ‘s suggestion and indeed interp does the job. For sure his solution was workable and good. I just couldn’t see it because I was tired and stupid. I am sure this…
Having some problem to understand the x_bin in regplot of Seaborn
I used the seaborn.regplot to plot data, but not quite understand how the error bar in regplot was calculated. I have compared the results with the mean and standard deviation derived from mannual calculation. Here is my testing script. You can see the y and e from the two ways are different. I understand tha…
