In this post, we will see how to do matrix multiplication in C. If we want to multiply two matrices, then number of columns in first matrix must be equal to number of rows in second matrix. If this condition is not satisfied, below program will give you an error message. Here is sim...

I'm not sure if dividing the matrix up in this way has any use? But it seems to have a pattern and its interesting that the last part is a skew symmetric matrix usually associated with a vector 'cross' multiplication? Issues This assumes that the quaternion is normalised (sqw + sqx ...
