Solve matrix equations
This is an update of Mtrxedtr(). This program is a matrix editor, which I use as an alternative to the TI-89 Data/Matrix Editor. 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.

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.

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. The vector sum is copied to the home screen.
|vec_non3.zip||19k||06-10-15||Solve Systems of Non-Linear Equations & 2-D Vector Equation|

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.
