LININ
Type: Function
Description: Linear Test Function: Tests whether an algebraic is structurally linear for a given variable.
If any two subexpressions containing a variable (name) are combined only with addition and
subtraction, and any subexpression containing the variable is at most multiplied or divided by
another factor not containing the variable, the algebraic (symb) is determined to be linear for that
variable. LININ returns a 1 if the algebraic is linear for the variable, and a 0 if not.
Access: !°
