A, B and D are matrices of their own (3x3) Then the equation [E;K] = [A, B; B, D]^-1 * [N;M] is not mathematically defined. The inverse of a 6x6 matrix is 6x6. You cannot multiply this with a 4x5 matrix. Actually Matlab was devolopped for exactly such Matrix equations. ...
multiply 1 by 5 by 9 on the first diagonal to get 45. Multiply 2 by 6 by 7 on the second diagonal to get 84. Multiply 3 by 4 by 8 on the third diagonal to get 96.

For the rotation, I am converting the quaternions to rotation matrices using the build_rotation function, and then applying the same 3x3 rotation matrix, then converting back to quaternions: new_rotation = build_rotation(gaussians._rotation) new_rotation = rotmat @ new_rotation gaussians._rotatio...
Multiply the values along each of the bottom-left to top-right diagonals Add together the values found in step 4 Add together the values found in step 5 Subtract the value found in step 7 from the value in step 6, and simplify
In this code, you are creating a 3x3 array arr_1 storing the values from 1 through 9. Then, you create a 2x2 slice of the original array storing from the second value to the end in both dimensions, arr_2. Notice that the Python indexing is 0-based, so the second element has the...
