3. Create a 3x3 rotation matrix from a unit 3-d vector and an angle in radians. 4. Perform matrix multiplication. > It seems to me that perhaps numpy should be able to help me with this. However, I can only figure out how to do 1 and 4 using numpy. Meybe someone knows a way t...
Thenormalize()function scales vectors individually to a unit norm so that the vector has a length of one. The default norm fornormalize()is L2, also known as the Euclidean norm. The L2 norm formula is the square root of the sum of the squares of each value. Although using thenormalize(...
