solvefor  solve for one or more of the variables found in a set of equations

Calling Sequence


solvefor(eqn_1, eqn_2, ... )
solvefor[varseq](eqnset)


Parameters


eqn_1, eqn_2, ...



equation or a set of equations to be solved collectively

varseq



expression sequence of variables to be placed on the leftside of the equations forming a solution

eqnset



expression sequence; one or more equations to be solved collectively





Description


•

Important: The solvefor command has been deprecated. Use the superseding command solve instead.

•

The solvefor command isolates specified variables (if any) from a set of equations on the lefthand side of a reduced set of equations. If no variables are specified it is essentially equivalent to a call to solve. Answer are returned in a form suitable for use in other commands such as subs and eval.

•

The original set of equations is formed by collecting the arguments to solvefor into a set of equations. The solve command is applied to the resulting system to produce 0 or more solutions.

•

If no solution is found this is indicated by an empty list. If more than one solution is found then they are returned as a list of solutions.

•

Each solution is returned as an equation, or (if more than one equation is involved) as a set of equations in which the variables on the lefthand side do not appear on the right hand side.

•

Variables may be specified as an index to the procedure name, as in solvefor[x](...). This indicates that the solutions must include the indicated variables on the lefthand side of the solution equations.
