MtrxCal

MtrxCal takes calculations on the palm platform to a whole new level.

Don’t spent hours writing a program for some programmable calculator while MtrxCal can perform the same calculations with just a few simple lines. Don’t waste time trying to find the right maximum and minimum values for plotting your functions. Just let MtrxCal use its build-in auto-scaling feature. The syntax for adding two values and adding two matrices containing hundreds of values is the same. Define a range like x=[-6:0.1:6] and calculate the sinus of this matrix like y=sin(x). Now you can just plot all the values with the command plot(y) or plot the power of y using the command plot(y.^2)

A Brief Introduction to Applications of Linear Algebra
By James Derry

Matrix calculations
No tables or different screens to enter the values for a matrix just type A=[2 3; 4 5], for example, to fill a matrix and type det(A) to calculate the determinant.
Create your own keypad
Button size will adjust to number of buttons.
Autoscaling
x=[-4:0.1:4]; plot(x,x.^2) See screenshot!
Logarithmic scaling
Even logarithmic scaling is supported for the x-axis and the y-axis.
Solve linear equations
[2 3;1 -1]\[14;-3] solves for 2*x+3*y=14 and x-y=-3 See screenshot! Complex numbers
t=[0:0.1:2*pi]; plot(exp(1j*t))  These short functions will plot a circle using an matrix containing complex numbers.
Select from four different user configurable screens
Select a special screen for matrix calculations, for scientific calculations, basic calculations or just define your own screen with your own buttons for your own needs.
Built in memopad-like database
Store your programs in different categories for easy access.
Initialize program
Each time you start MtrxCal a program called Initialize will be executed. This is where your can initialize MtrxCal according to your own needs.
