1.60	BETA	Screen capture added to the windows version. Fixed bug when switching between modules Changed result of (-1)^.5 for classic and matrix module Added functions classic module subplot() Use subplot instead of gstdc() xlabel(string) add text at x-axis ylabel(string) add text at y-axis. Added functions matrix module subplot() fft() and ifft() fourier and inverse fourier functions freqs() Calculates frequency response of analog filter. freqz() Calculates frequency response ofdigital filter. impz() Calculates impulse response of digital filter. Several window functions used for digital filtering. Carriage returns are ignored between []-brackets. All elements of a bigger matrix do not have to be on one line anymore.

1.54	08/06/2004	Fixed bug using scrollbars for palm version. Updated user manual. Little fix in Engineering display format. Added initialization files. (See startup sequence in usermanual) Tap inside active graph and x,y value will be shown at bottom of screen. Added functions classic module gxlog(), gylog() - set log scale. Call before calling gaxis() gwtap() - wait till user taps in active graph gtapx() - returns x-value of cursor position gtapy() - returns y-value of cursor position init() - returns 1 only the first time called in scrip

1.51	06/11/2004	Some minor enhancements for the palm version.

1.50	06/01/2004	Enhanced error detection in the matrix and classic module Updated user manual Several fixed for the inpv() function used in the classic and matrix module. Refresh of graphical screen, switching between applications, problem fixed. Fixed small bug in PDAcalc units after switching between modules Added functions in the matrix module: bar(x,n) and [n x]=hist(y) polar(theta,rho) polyfit(x,y,degree) besselj(n,M) bessel of the 1st Kind function n=cond(M) returns the condition of a matrix M=load('file') and save('file',M) functions to load and save the contents of a matrix

1.49	04/23/2004	Some changes in registration routine. You will need to enter your registration code again after installing this version. Edit bug fixes for palm version. Changed division by zero for matrix module. Does not stop execution but shows NaN (Not a number) or Inf (infinite) Improved error checking of the matrix module. Fixed lt=>cup conversion bug in units module. (Palm only) Few minor updates for classic module.

1.47	02/25/2004	User functions and calculus functions added to the matrix module. Several example scripts where added. Little updates to the classic module. Few updates for the tungsten palm os devices

1.45	01/10/2004	Fixed gal=>lt conversion problem in PDAcalc units. Several updates for classic and matrix module.

1.42	12/20/2003	Added the Matrix module.

1.34	10/03/2003	Several fixes to synchronize the scripts between the windows version and the palm version. Added the ability to change the scripts directory in the windows version to synchronize scripts with the PocketPC. Several minor bug fixes.

1.30	08/30/2003	Fixed problem some people reported with uploading and downloading script from our web site. The new version for the palm os devices contains both modules classic and units. No need to install both modules anymore. Just select the module from the options menu. The previous version number of PDAcalc units was 1.22. Since they are both combined now we had to make the version of PDAcalc higher than 1.22 Refresh problem fixed in palm version. (Screen was refreshed more often than necessary which caused the blinking of the screen) Added extra selection on the preference screen of the units module. Now you can select between UK and US units.

0.82	08/06/2003	PDAcalc classic user manual added Several updates for the pocketpc version. Functions date(mm,dd,yyy,text), exit(text) and error(condition,text) added Pressing the basic operators, + - * /, when the scratchpad is empty the previous result will be put in the scratchpad first. Press [CLR]+5[EXE][EXE] to see how this works.

0.80	07/28/2003	Fixed memory leaks. Conduit, synchronization between palm and windows version, changes. Please be careful using the conduit since we still need to do more testing. Fixes for high resolutions screen on sony NX70 Pocketpc fixes for SIP, Supplementary Input Panel. Changed setup program to install without pocketpc after ActiveSync is detected.

0.70	07/01/2003	With this new beta version you can just add strings together like: res='len='+123+' yards'. This eliminates the need for two string arguments in functions like gprt(x,y,str1,str2) because you can just use a plus sign between str1 and str2 instead of using a comma. Even better you can use as many string you want as long they are separated by a plus sign. The main concern was compatibility but we think the advantages are far greater than the disadvantages. This is why the number of arguments where change for the function gprt(),gcprt(),glprt(), gtadd(),result(), mode1() and mode2() Added a few more links under the help menu on the windows version. Fixed rnd() bug on palm version.

0.55	06/10/2003	Added ssave(file) function to save the statistical data. Improved sdata() function to avoid reading errors of the data file.

0.54	05/02/2003	Added color argument to gpnt() function. First argument is color. Fixed mod() function. The arguments where swapped.

0.53	04/30/2003	Added 3D function plot Several updates to prevent premature termination of program due to memory allocation problems. Added error message when variable table is full. You can just clear the the variables in the variables screen and continue. This can happen after loading several programs since the variables are not cleared before a program is loaded.
