Matrix 2d flash game

The equations for changes in the and coordinates are: 3. As before, we consider the coordinates of the point as a one row two column matrix and the matrix. We next define a J monad, scale , which produces the scale matrix. This monad is applied to a list of two scale factors for and respectively.

The translation equations may be written as: 5. We wish to write the Equations 5 as a single matrix equation. This requires that we find a 2 by 2 matrix,. From this it is clear that and , but there is no way to obtain the term required in the first equation of Equations 5. Similarly we must have. Therefore, and , and there is no way to obtain the term required in the second equation of Equations 5.

What is required at this point is to change the setting 2D coordinate space in which we phrased our original problem. In geometry, when one encounters difficulty when trying to solve a problem in space, it is customary to attempt to re-phrase and solve the problem in space.

In our case this means that we should look at our 2D problem in 3 dimensional space. But how can we do this? Consider that, given a point in 2 space, we map that point to. That is, we inject each point in the 2D plane into the corresponding point in 3 space in the plane.

Performance Performance. It was intuitive. Kind of charming. A majestic creature, finally freed from its n x m rectangular cage. So, I made this little matrix toy. Hopefully this helps someone else figure out matrices, or maybe everyone else except me already found matrices intuitive.
