WebIn Matlab this would be possible with the corr function corr(X,y). For Python however this does not seem possible with the np.corrcoef function: import numpy as np X = np.random.random([1000, 10]) y = np.random.random(10) np.corrcoef(X,y).shape Which results in shape (1001, 1001). But this will fail when the dimension of X is large. WebSelecting random elements from an array. Assign selectedValues with numberSelected randomly selected elements from row array dataSet. Duplicate selections are acceptable. Hint: Use the randi function and an indexing array. Ex: If numberSelected is 3 and dataSet is [ 74, 13, 1, 51, 6], then selectedValues might return [ 1, 74, 13].
