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)
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 you start MtrxCal a program called Initialize will be executed. This is
where your can initialize MtrxCal according to your own needs.
Upload your programs to our web site and receive a free registration
code
It was never so easy to upload programs directly from a palm database to a web
site.

What makes MtrxCal really so special?
It is easy to have the palm perform more advanced calculations then ever before. Please see documentation in download file for more information.
