ABAM 1.0   (details) 49/50 ENG   2,179 KB / 5 KB
EULER, RK4, and ABAM will produce an XY matrix of data points. These points have been calculated using the associated formulas, which have been created to solve differential equations that cannot be solved by standard techniques. This data consists of a series of x iterations with its corresponding y value. The criteria for the input is a first degree differential in the form of "y' =without the "y' =" ie. 'dy/dx = X + Y'. Simply enter 'X+Y' for the input equation. Secondly, it is necessary to have x initial, y initial, x final, and an iteration size. The accompanying literature should give enough detailed information. This XY output may then be seen with PLOTT.
