This option is for solving equation systems.
It uses the functions selected before opening of the dialog.
In the function window only functions (Name = Term) can be entered. For the solving, in many cases the equation system is available with equations (Term = Term). For that purpose a equation window can be created which supports the entry of equations (Menu "Edit"->"New equation window").
Solve for | Enter the label that shall be solved for |
Keep | The labels that shall not be eliminated. |
Keep together | Additional labels that shall not be eliminated. These parameters are tried to be kept together during term optimisation, which may improve readability of the result. |
Definitions | Here additional functions can be entered. This may be useful if the same equation system needs to be solved for different cases. For this also the field "Template" is used. For the given template name all settings of the dialog are saved, so that it is available for the next opening of the dialog. For templates an additional comment is inserted including the additonal parameters with the solved function.. |
The options control the solving step and the result.
Wit the 'Cancel' button the solving process can be stopped.
Example:
For the equations
A = x
C = 5
C = [A]-[B]
With settings 'Solve for' "B" and 'Keep' "A,C" the result is
B = -[C]+[A]
With settings 'Solve for' "B" and 'Keep' "" the result is
B = x-5
