3D Shape Rotator 1.0   (details) 49/50 ENG   8KB/2KB
ScreenshotThis program can rotate any 3D object given as matrix of coordinates about the x y and z axis.

Convolucion 1.0   (details) 49/50 ESP   86KB/1KB
ScreenshotShows the convolution of two functions graphically.

Critical Points 1.00   (details) 49/50 ENG   2KB/1KB
ScreenshotCP is a simple User RPL program that attempts to find the critical points for any given function. It also gives the local Maximum and Minimum points, and F(x) at these points. It is handy for high school students to verify they have the right answer in exams. CP also complements the built in grapher, by giving exact answers for critical points.

DRAW3DMATRIX   (details) 49/50 ENG   16KB/20KB
A 3D renderer written using HPGCC3 with grayscale graphics and proper polygon sorting. Written with HPGCC3 for the 50g only, requiring a custom ROM to run.
Author unknown. 2017/12/17

geohp 1.1   (details) 49/50 ENG FRA   225KB/89KB
ScreenshotDynamic geometry software (like geogebra). You can create geometrical figures with lines, circles, curves and move a point. Zoom in/out, scrolling, moving a point are made in real time (with 16 grey levels). Program and documentation are in English and in French. Written with HPGCC for the 49g+ and 50g only.

GWnds   (details) 49/50 ENG ESP   6KB/4KB
Adds some commands that recall the 49's graph windows and optionally binds them to user keys. Evidently this person did not realize you could hold down the shift key to access the graph windows in RPN mode.

HLDRAW 2.6   (details) 49/50 ENG   15KB/3KB
ScreenshotHLDRAW does what WIREFRAME should have done: fast, true photographic, hidden line removed 3D plotting. It is possible to easily adjust the viewpoint so that you can rotate the graph.
By Jurjen N.E. Bos. 2001/05/21

HLDRAW 2.61   (details) 49/50 ENG   17KB/4KB
ScreenshotEquivalent to WIREFRAME plot, but with hidden line removal and shading of "underside" of 3D graph. For the 49g+ and 50g (ROM 2.15) only. The previous version only worked on older ROM revisions (older 49G ROMs only?). Modified to work with most current ROM. Source code has been updated as well (for on-calc compiling only).

INT1D 1.0   (details) 49/50 ENG   102KB/1KB
Fast plotter and numerical integrals and sums of algebraic expressions using hpgcc2. Speed is 50 to 100x faster than User RPL. Sums from 1 to 100,000 in about 1 second. For the 50g and 49g+ only. Runs in RPL with stack entry mode. SD card is required (takes 80KB on the card). Full C-source is included

LOGPLOT 2.05   (details) 49/50 ENG   56KB/9KB
ScreenshotThis library makes log-scale graphs for the 49G/49g+/50g. Plot types "Function", "Scatter" and "Parametric" are implemented. In the type "Function", TRACE and (X,Y) in the 49G plot menu are available. Non-uniform logarithmic tick, zoom-in, zoom-out and recenter are implemented. Faster than previous versions.
By Takashi Matsubara. 2007/08/04

Mandelbrot Beta   (details) 49/50 ENG   2KB/1KB
Plots the Mandelbrot set (or any part of it) in grayscale. In ASM.
By Tanguy Briancon. 2001/02/26

mc 1.00   (details) 49/50 ENG   54KB/64KB
The program implements the marching cube algorithm: it extracts an isosurface from its implicit equation f(xyz). For the ARM-based calculators only.
By Patrick Offret. 2009/07/12

Plot 0.0.1   (details) 49/50 ESP   3KB/3KB
Plot is an application to plot signals (continuous, piecewise, singular, etc).
By Roberto Eduardo Saravia. 2002/05/21

Plot 49   (details) 49/50 ENG   3KB/2KB
ScreenshotFront end to the 49's plotter that allows you to navigate around a graph, scrolling the screen.
By Frédéric Saverot. 2000/07/01

plotxyz 1.01   (details) 49/50 ENG   51KB/48KB
Plots parametric equations in the form x=(u,v) y=(u,v) z=(u,v). For the ARM-based calculators.
By Patrick Offret. 2009/06/27

Root Locus Plotter 1.03+   (details) 49/50 48 ENG   30KB/8KB
Root Locus plotter. It also figures out the angles of departure, asymptotes, etc.
By Jason Frandsen. 2001/12/20

Scatter 1.1   (details) 49/50 ENG ESP   5KB/3KB
Automatically draws a scatterplot with the data of SDAT. First draws the points and then you can choose the type of regression for the graphic. Also, you can simply join the points of the graphic.
By Rubén de la Rosa Steinz. 2000/09/11

Scatter49 3.0   (details) 49/50 ENG   74KB/6KB
ScreenshotPerforms Scatter plots with several different mark styles (circles, diamonds, balls, boxes, etc).
