PDAcalc matrix

Use PDAcalc matrix on your pocketpc, palm OS device, laptop or desktop. The functionality of PDAcalc classic is not dependant on the platform it is used on. A script written on your palm OS device works exactly the same on a Pocketpc and a laptop. However a 800Mhz Pentium can process the scripts a bit faster than the processor in a palm OS device.

The only difference between the platforms is the speed and the amount of memory available for the scripts.

Warning!!!
If you are looking for a calculator to perform basic calculations
PDAcalc matrix is not for you!
PDAcalc matrix is way to powerful and to expensive to just balance you checkbook.

If you are using a windows system please download and install PDAcalc matrix (Windows). This windows setup program will detect the presence of a palm device and/or a pocketpc device and install PDAcalc classic accordingly. To register please run the windows version and select Register from the Options menu. Select Register online and follow the instructions.

• Roots function
  roots([1 -1.43 0.49]) finds the roots of x^2-1.43x+0.4

• Complex numbers
  t=[0:0.1:2*pi]; plot(exp(1j*t)) These short instructions will plot a circle using an matrix containing complex numbers.
  
  
• Solve higher order differential equations
  A 'spring damper' example is included in the mechanical category of the build-in database.
