Variable Clearing Functions
• clear(x, y, ...)—Clears variables x, y, ..., both symbolically and numerically.
• clear.sym(x, y, ...)—Clears variables x, y, ..., symbolically but not numerically.
Arguments
• x, y are any variables.
• For the clear function, the argument can be a system variable: TOL, CTOL, ORIGIN, PRNPRECISION and PRNCOLWIDTH. Clearing a system variable restores its default value.
Additional Information
The clear and clear.sym functions can only be used by themselves, and not as part of another expression, evaluation or definition.
