This application grew out of the fact that I have been taking linear algebra and many time have wanted to have a quick and simple linear algebra solver on hand to check my numbers, but due to the limitation of time and my coding skills with Actionscript 3.0 I had to keep the solver I wrote limited to 2x2 matricies. Eventually I might revisit the project and change it so the user cna imput matricies of any size he wishes to imput.
This application makes use of the Number class to solve some relitivly simple linear algebra problems. The user gives the problem two 2x2 matricies, A and B. After doing that the user hits the solve buttong and then the program calculates the transpose, represented by a "t" when I talk about a transposed matrix from here on out, of both matricies and then solves for the matrix multiplication of A*A, B*B, A*B, At*At, Bt*Bt, and At*Bt.
The program can be used multiple times, so you can imput as many matricies as you wish, as long as they are 2x2 matricies, the solve button just has to be hit every time there are new matricies to solve for.
This project is a modified version of the Temperatur converter.
The math here is relativly simple for someone who has take a linear algebra course, but the algorythm for multiplying matricies in is most general form is you take a row of yoru first matrix and a column of your second and find the dot product of them and put the value in the appropriate place in the result matrix.
The programming is relativly simple. It really just repeats the code nessare to get a number from an imput text field and then just performs the algorythm to get the correct values out for a matrix.
