Finding the cosine distance of a vector with multiple vectors in a matrix
I want to calculate the cosine distance of a vector with multiple vectors in a matrix.This is my matrix:
[[[ 0.04379608]
[ 0.02680701]
[ 0.33135787]]
[[-0.07822198]
[-0.12229042]
[-0.14169733]]
[[ 0.06672882]
[-0.05079487]
[ 0.06437925]]
[[ 0.04095123]
[-0.16082226]
[-0.04795549]]]
now I want to compare the first vectors cosine distance,
[[ 0.04379608]
[ 0.02680701]
[ 0.33135787]]
with other vectors. Similarly, I want to compare the second, third and fourth vector with each other by a for loop. This will produce five points.Thanks in advance.

Is there a reason this is tagged Python? Or are you looking for MATLAB only?

For Matlab, checkpdist2with the'cosine'option. That will avoid the need for a loop
