Laplace and Z transform R7		(open this file in DOS MODE)

Works on TI89 and TI92P, AMS 1.0x without installed kernel.
On AMS 2.0x needs any kernel like DoorsOS, UniOS or KerNO.
Doesn't work on TI92P, AMS 1.00.

Installation:

	Send file named lztr7.89g to your calc
	on calc: Run lzt\install() and choose "Archive"

	Check by pressing MODE if these options are set before using:
		!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
		!!!	ANGLE to RADIAN          	!!!
		!!!	COMPLEX FORMAT to RECTANGULAR 	!!!
		!!!	EXACT/APPROX to AUTO          	!!!
		!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Included function:

	ltrn( f(t) , t , s )		Laplace transformation
	invl( F(s) , s , t )		inverse Laplace transformation
	finvl( F(s) , s , t ) 		fast 	- || -
	ztrn( f(k) , k , z )		Z transformation
	invz( F(z) , z , k )		inverse Z tr.
	finvz( F(z) , z , k )		fast inv. Z tr.
	heav2dir( f(k) , k )		heaviside -> discrete dirac


FAQ:

Q:	It produces an error "Invalid program reference"
A:	It means that you are using Advanced Mathematics Software (AMS) 2.0x
	without any installed kernel.
	Install any kernel (DoorsOS, UniOS, KerNO)
		
		Unzip file DISTRIBUTED_FILES\kerno.zip.
		Send and run file kerno.89z for HW1 calc or
		hw2kerno.89z for HW2 calc.
