This is an experimental solver for sets of linear equations whose
coefficients and constants are to be precalculated in terms
of other parameters, which may be nonlinear.
Enter the parameter evaluation formulas in left hand box. Any valid
variable names and expressions may be used in the course of evaluation.
The parameters must have the special names "_1", "_2" etc.
Each formula should be on a separate line or separated by a ";".
Enter the equations in the middle box using the syntax of the
example. The unknowns must be called x1, x2, etc. A parameter
may appear anywhere instead of a number.
Each linear equation should be on a separate line, with unknows on the
left hand side, and constants on the right hand side
Click 'Precalc to evaluate parameters; their values will appear
in the right hand answer box.
Click `Solve'.
The solution will appear in the right hand
box.
Saving this window will not save the contents of the boxes, but you may use the `Copy' and `Paste' keys to copy your equations and/or solution
from there to another document.
