Is my output of librosa MFCC correct? I think I get the wrong number of frames when using librosa MFCC
The signal is 1 second long with sampling rate of 16000, I compute 13 MFCC with 400 hop length. The output dimensions are (13,41).

Calculate the cumulative sum of multiplying each element of one array by all the elements of a second array
I need to efficiently calculate the running sum of multiplying the elements of one array by all the elements of a second array. It is probably easiest to explain what I am trying to do with code: My ‘a’ array will typically be big so I would like this to run as fast as possible, but right now it is
