ExpressionLinearSolve(R, F)

expr.spad line 1167 [edit on github]

• R : Join(IntegralDomain, Comparable)
• F : FunctionSpace(R)

Solver for linear systems represented as list of expressions.More efficient than using solve because it does not check that system really is linear.

lin_sol : (List(F), List(Symbol)) -> Union(List(F), "failed")

lin_sol(eql, vl) solves system of equations eql for variables in vl. Equations must be linear in variables from vl.
