To vectorize the given update loop, we can leverage NumPy's array operations to eliminate the need for the explicit loop. Here's how you can achieve that:
1 2 3 4 5 6 7 8 9 10 11 12 13 | import numpy as np def update(high, highest_number, delta): # Create a boolean mask to select all indices except highest_number mask = np.arange(len(high)) != highest_number # Calculate the updated values using vectorized operations updated_values = np.minimum(high, high[highest_number] + delta[highest_number] - delta) # Apply the mask to update only the required elements high[mask] = updated_values[mask] return high |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 | import numpy as np def update(high, highest_number, delta): # Create a boolean mask to select all indices except highest_number mask = np.arange(len(high)) != highest_number # Calculate the updated values using vectorized operations updated_values = np.minimum(high, high[highest_number] + delta[highest_number] - delta) # Apply the mask to update only the required elements high[mask] = updated_values[mask] return high |
