I have an array xi
xi=
[[ 0.49671415 -0.46341769]
[-0.1382643 -0.46572975]
[ 0.64768854 0.24196227]
[ 1.52302986 -1.91328024]
[-0.23415337 -1.72491783]
[-0.23413696 -0.56228753]
[ 1.57921282 -1.01283112]
[ 0.76743473 0.31424733]
[-0.46947439 -0.90802408]
[ 0.54256004 -1.4123037 ]]
then another array yi
[0 0 0 0 0 0 0 0 1 1 1]
how do I slice the xi array into 2 based on 0 and 1 in yi? how can i have
x1=
[[ 0.49671415 -0.46341769]
[-0.1382643 -0.46572975]
[ 0.64768854 0.24196227]
[ 1.52302986 -1.91328024]
[-0.23415337 -1.72491783]
[-0.23413696 -0.56228753]
[ 1.57921282 -1.01283112]
and
x2=
[ 0.76743473 0.31424733]
[-0.46947439 -0.90802408]
[ 0.54256004 -1.4123037 ]]
Thank you for your help!
You can use:
x1 = xi[~yi.astype(bool)]
x2 = xi[yi.astype(bool)]
