The solutions are copied to the home screen, using Copyto_h() by Samuel Stearley, so they can be more easily used in further calculations. The only negatives are that the unknowns must be x, y, and z and that it does not work well for trigonometric equations.

The function returns an MxN matrix whose column vectors are a set of orthogonal vectors which are computed from the argument using the Gram-Schmidt process. For example,If the column vectors of the argument are the basis of some subspace, then the column vectors of the returned matrix form an orthogonal basis for the same subspace. It would be nice if the function could work with a list of vectors, but, in the ti-89 a list can not have vectors as elements.

I use it as a keyboard program so it's easier to access and use than the Data/Matrix Editor. You can create and edit a matrix, edit an existing matrix, insert rows or columns, and check dimensions easily even when the matrix is too large for the screen. You don't have to name the matrix before it is created so you save a few steps and time. The matrix is automatically saved as "z", unless you choose to change it. This update improves the editing process and changes the display to allow you to scroll through a large matrix.

simul_mn.zip	7k	04-02-27		Simultaneous Linear Equation Solver This program provides modified input, output, and editing systems for the TI Flash Apps Simultaneous Equation Solver. This update addresses 2 problems. 1. The lockup problem sometimes encountered when using complex coefficients in the Apps program. In Simul_mn() v. 1.2, complex coefficients can be now entered in either polar or rectangular form. Results can be toggled between polar and rectangular. 2. The alpha lock problem which occurred ( even with autoaoff() installed ) when the program was run by using Catalog, F4. Alpha lock now remains off. Results are copied to the home screen. Results and the original augmented matrix are saved automatically. This eliminates the bother of naming a variable each time you save results. Coefficients can be entered directly or as a previously stored augmented matrix. Coefficients can be edited by rows. Results can be toggled between auto or approximate form. Solutions to dependent systems are given in terms of arbitrary constants. To use Simul_mn(), you must have TI Flash Apps Simultaneous Equation Solver installed on your calculator.

This is actually an update from the last time I had posted it, I found a bug in it, bt now it runs fine. It is avery clean program, it is small and deletes all the variable that it creates so you dont have to go and delete things every time you run it. I made it for my upcomming math test, but anyone who has alg. eould find it usefull so give it a try!cool.
solvnon3.zip	4k	06-09-24		Solve Systems of Non-Linear Equations This update fixes a couple of minor problems.

Any unknown angle must be represented by x. The domains of x, y, and z can be set as desired. For angles, the default domain is 0 to 2pi, but can be set by quadrants, or any values you want. Solutions are copied to the home screen, so they can be more easily used in further calculations.

This results in the vector part being easier to use. It solves vector equations (with no more than one unknown angle). It finds real solutions of n x n systems of simultaneous, non-linear equations, for n=1,2,3. It can handle various types of equations, including trigonometric equations (with no more than one unknown angle). The unknowns must be represented by x, y, and z. Any unknown angle must be represented by x. The domains of x, y, and z can be set as desired. For angles, the default domain is 0 to 2pi, but can be set by quadrants, or any values you want. Solutions are copied to the home screen, so they can be more easily used in further calculations.

To simplify keystrokes, that is, to avoid hunting for the angle symbol, Ð, polar form is entered as r,,q and rectangular components as x,y. Note the use of 2 commas instead of , Ð in polar form. Entries can be edited. As each vector is entered, the sum of all vectors entered to that point is displayed. Subtraction can be included by entering the magnitude as a negative quantity. Results are copied to the home screen in both forms. This update also addresses the alpha lock problem which occurred ( even with autoaoff() installed ) when the program was run by using Catalog, F4. Alpha lock now remains off.

This update allows the input of vectors (or complex numbers) in either polar or rectangular form. To simplify keystrokes, that is, to avoid hunting for the angle symbol, Ð, polar form is entered as r,, q and rectangular components as x,y. Note the use of 2 commas instead of , Ð in polar form. Entries can be edited. Results are copied to the home screen in both forms. After all vectors are entered, the vector sum is displayed and two types of vector diagrams are drawn. The first diagram displays each of the vectors in standard position at the origin. The second diagram is the vector polygon formed by the vectors and their resultant.
