FilledSmallSquareLinearExpressionToMatrix[expr, vars] gives m, c where m . vars - c == expr.

FilledSmallSquareLinearExpressionToMatrix[expr] deduces variables using Variables[expr].

FilledSmallSquareexpr must be a linear function of the variables vars.

FilledSmallSquareLinearSolve[m, c] gives the solution to Thread[expr == 0].

FilledSmallSquare With the option WorkingPrecision -> n explicit numbers with more than n digits of precision are reduced to n-digit precision.
