| **linsys.zip** | 1k | 06-08-20 | | **Linear System Solver** Solves linear systems of equations. Enables you to enter in complex values as well since the TI-83 is incapable of complex values in matrices. Perfect for electrical circuits. |

| **echelon83.zip** | 1k | 04-01-08 | | **Matrix Reduction** Reduces a matrix to echelon or reduced echelon |

| **compnumbers.zip** | 1k | 03-03-12 | | **Complex Numbers** Complex Number program which equates Cartesian to Polar, Polar to Cartesian, z1.z2, z1/z2 and De Moivre's Theorm AND Gives answer in Polar & Cartesian. Good for VCE/HSC Specialist maths |

| **eigen.zip** | 1k | 03-03-06 | | **Eigen Values** This program finds the two Eigen values of a 2 x 2 matrix. Works for non real values too. |

| **cpxsis.zip** | 6k | 02-10-15 | | **CPXSIS** Do you want to solve a system of linear equations with both real and complex vars, in an easy way and without the writing of matrices?. This program uses the Gaussian partial pivoting technique to make it. If it is not enough, you can also choose between polar and rectangular format on displaying results. |

| **imatrix.zip** | 2k | 02-09-30 | | **iMatrix** solve matrix with complex numbers |

| **eye.zip** | 1k | 02-01-01 | | **Identity Matrix Creator** This program creates an identity matrix of specified size. It stores it as matrix [I]. |

| **simeqatn.zip** | 1k | 02-01-01 | | **Simultaneous equations solver** Solves simultanes equations and give interception |

| **lqs.zip** | 1k | 01-06-27 | | **Linear-Quadratic Systems** Solve system of equations. |

| **sys23.zip** | 1k | 01-02-07 | | **System of Equations** I think this is the shortest program out there that would solve system of equations in 2 and 3 variables. I used the rref function. |

| **system.zip** | 1k | 01-01-04 | | **System of Equations** This program would solve system of equations in 2 and 3 variables. Very easy to use. |

| **mag.zip** | 1k | 00-11-23 | | **Mag** Finds the magnitude of a vector and gives the answer as the square root of a number and also the decimal answer. |

| **vectors1.zip** | 2k | 00-11-09 | | **Vector Solver** This program will add and subtract any number of vectors you need, it will also multiply a vector by a coefficent and then add or subtract it. A must need for anyone in pre-cal or physiscs!! |

| **vectors.zip** | 1k | 00-10-07 | | **Vectors v1.0** This program will find the magnitudes, dot product, cross product, projection, and angle between any two vectors you supply. Great for Calculus 3. |

| **determ.zip** | 1k | 00-09-02 | | **Determinants v1.2** This is a program that can find X, Y, and Z(if applicable) in a second and third order equation and finds the determinants. *update* program is 90 bytes bigger than V1.11 but saves about 400 bytes RAM overall. |

| **cramer.zip** | 1k | 00-07-14 | | **Cramer's Rule v1.10** This program solves for a system of linear equations using Cramer's Rule. |

| **imagine83.zip** | 1k | 00-06-23 | | **Imagine83** Find the modulus and argument of complex numbers, a+bi equation for mod and arg, and complex and real roots of quadratics |

| **matsolver.zip** | 1k | 00-04-17 | | **Matrix Solver** This program uses matrices [A] [B] and [C]: Add, Subtract, and Multiply both ways. It also finds and displays (ODTAI): Original, Determinent, Transpose, Adjoint, and Inverse of a matrix. The biggest time saver is that this program finds the Echelon form of a matrix as well as show each step. BIG TIME SAVER!!!! |
