|Reads the scatter data in the 'sDAT' (SigmaDAT) variable and performs a connect the dots output. The user can scale and translate the graphical output exactly like any normal graphical operation.|

|Method of Weighted Residual (details)
||28 ENG 579KB/1KB|
|Prior to development of the Finite Element Method, there existed an approximation technique for solving differential equations called the Method of Weighted Residuals (MWR). For Galerkin's method, the test function w comes from the chosen trial function, i.e. w = du/da and the weighted average of the residual over the problem domain is set to zero. This program returns the trial function. It is shown plotted with the exact solution for 0<x<1.|

|Collection of some programs on statistics, which computes functions and derivations of x/y-data and draws them.|

|Tiny Multiple Equation System Solver 1.0 (details)
||49/50 48 28 ENG 3KB/1KB|
|Tiny MSLV (multiple equation solver) for all RPL calculators. Program is 333.5 bytes on the 48GX. On the HP-28C it can find a simultaneous root of five nonlinear real-valued expressions. Uses successive approximation and the calculator's built-in matrix functions.|
