Card Sharks Odds   (details) Prime ENG   3 KB / 2 KB
The game show Card Sharks may have long been off-air except for reruns on GSN or BUZZR (or even finding videos on YouTube), the game show is still popular. It is a simple game involving a standard deck of 52 cards. The object is to predict whether the next card is higher in rank or lower in rank than the preceding card. In Card Sharks, aces always count as high. Along with aces, twos are very desirable, while eights are the worst cards in the deck. The program CSODDS tracks the odds of whether the next card is higher or lower. CSODDS assumes a 52 card deck (no jokers).

Control System Programs   (details) Prime ENG   16 KB / 36 KB
Ten programs that could potentially be useful for anyone in a control systems class. The first program takes as input the system matrix (a) and the input matrix (b) to find the controllability matrix. With it there is another function that will check if the controllability matrix found is controllable or not. The next program takes the system matrix (a) and the output matrix (c) as inputs to find the observability matrix. Along with it is another function to check if the observability matrix is observable. The third function uses Ackermann's Formula to find the feedback constants. It takes as input the system matrix (a), the input matrix (b), and the desired characteristic equation coefficients. The other programs convert the system from a statespace model to a transfer function, convert the system from a transfer function to statespace form, create the Routh table from the characteristic equation, find the Static Error Constants (Kp - position, Kv - velocity, Ka - acceleration) and also their respective steady state errors (essp - step, essv - ramp, essa - parabola), solve for all possible input combinations to solve for a second order system, graph the step response of the transfer function, and find the step response characteristics of the step response graph.

Open loop response with and without controller and resulting closed loop response (unity feedback loop) can be determined / compared. The app takes as input the transfer function of a process as well as the settings of a (PID) controller. It includes a ‘Bode plot’ which combines magnitude and phase plots on the same screen, indicating real frequency (log scale) and magnitude (log or dB scale) values, and not the logarithm of these values, although logarithmic scales are used. This Bode plot does not rely on the built in HP Prime plot mechanism but is programmed from scratch, including mouse movement and key press detection and custom soft key menus to accomplish functionality that would not be possible otherwise. The app also draws Nyquist and Nichols plots. Includes PDF documentation.

Calculates the nodal period of a satellite using a numerical integration technique. The algorithm first uses the RKF78 method to propagate the first-order perturbed equations of satellite motion forward in time to bracket a "nodal objective function". Once a bracket is found, the algorithm then uses Brent's root-finding method to find the time at which the objective function is zero to within a user-defined tolerance. While looking for the root the software also uses the RKF78 method to propagate the satellite's orbit subject to the main oblateness gravity perturbation of the Earth.

PLUNGE 1.0   (details) Prime ENG   5 KB / 8 KB
ScreenshotCalculates the time-to-fall in a plunge orbit (eccentricity=. The zip file contains two programs. PLUNGE1 requires input values for the initial separation where two objects are at mutual rest, and for the separation between those same objects at two subsequent times prior to contact. The code calculates the amount of time to fall from the initial separation to each of the subsequent positions, and then it calculates the time difference; i.e. the amount of time to fall from the first subsequent position to the second subsequent position. PLUNGE2 requires input values for an observed separation and for an observed radial velocity (in approach) for that separation, and for a final separation. The initial distance is calculated using the Vis Viva equation. Then the amount of time required to fall from the initial separation to the observed separation is calculated. Next, the amount of time required to fall from the initial separation to the final separation is calculated. Finally the time difference required to fall from the observed position to the final position is found by subtraction.

Shadow Conditions of Earth Satellites - Kozai Orbit   (details) Prime ENG   369 KB / 85 KB
Accurate predictions of shadow conditions for any type of satellite orbit can be determined by using a combination of one-dimensional minimization and root finding. The algorithm used here searches for minimum values of the angle between the shadow axis and the satellite’s position vector as a function of time. If this angle lies within the penumbra angle, the algorithm uses Brent's root-finding method to look backward and forward relative to this minimum time to find entrance and exit conditions. This method can also be used to determine entrance and exit relative to the umbra, penumbra and cylindrical shadows.

Skeptic   (details) Prime ENG   15 KB / 2 KB
ScreenshotA method for combining experimental results. The idea is this: if we "trust" the values and error bars reported by the various experimenters, the usual recipe for computing a weighted average and overall error bar is fine. But if the error bars are inflated or deflated (intentional or unintentional), the Bayesian approach allows for some "slop" in the error bars and finds optimal agreement between the experiments. For instance, if one experiment reports a value with small error bars that is quite different from other experiments, the usual weighted average calculation will be dominated by that "rogue" experiment. This does not happen with the Bayesian (SKEPTIC) recipe.

Tunnel 1.05   (details) Prime ENG   2 KB / 5 KB
ScreenshotThis is the official release of the Prime port of the 39gII Tunnel clone written in BASIC, now adapted for the larger screen and color display. This new version adds speed throttling to ensure that the game runs as close as possible to the same speed as the original Prime on both the emulator and G2 hardware revision of the calculator. It is probably the first ever game ever made available for download for this calculator model. It isn't meant to show coding skills, especially considering the game was made before the author's knowledge of the DIMGROB_P and BLIT_P commands (although an intro transition using them was added afterward), but as you'll see on-calc, even if the entire screen content must be refreshed every frame, it still gets a high frame rate, because of how incredibly fast the calculator is, even with redrawing the entire screen rectangles and score text every frame. As for the multicolor and 3D-ish text effects, they are possible because the HP Prime lets you use text with no background, so all you have to do is superpose multiple copies of that text, gradually changing its color and position through a FOR loop. This also lets you use bold text. To play, just use the UP and DOWN keys and quit with ON.
