Exercise 3: Implement 12distance In this exercise, you will use the above formula to implement the function 12distance, which computes the Euclidean distance matrix D without a single loop. Recall that the element-wise square of D is of the form and the entries of D are DOD S+R-2G D₁j = √[DD]ij Hint: Make sure that all entries of D are non-negative after you take the square root √ [DOD];; because sometimes very small positive numbers can become negative due to numerical imprecision. Since all distances must be non-negative, you can simply overwrite all negative values with 0.0 to avoid unintended consequences.
