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.
