Python Numpy Where
[ad_1]
np.where
Oh right so we have a giant matrix A and another smaller matrix be in this video we’re going to use Np.where to change and manipulate the matrices how we want.
np.where can take in up to 3 parameters, the array of booleans, the array to keep values, and a replacement array. I will show you how it works with some examples.
all right so let’s going with our examples. First we will just give np.where a mask on b where b 0. This will give back indices where the condition is met.
Lets do the same thing with A
In this next example we will give a few more parameters .

I could do without the background music. This may all be ho-hum stuff to you, but it's new to me, and I'm into my 10th hour today studying. It is not helpful to have distracting music playing.
First rate videos, like always; thanks for sharing!
Thank you !! so helpful !! 🙂 🙂
