3.8.19. INTEGRAL
Computes the 1-dimensional integral of user function f from xlo to xhi. Just a stub at
present.
Syntax: INTEGRAL(f, xlo, xhi)
3.8.20. LN
Natural logarithm.
Syntax: ln(<expression>)
3.8.21. MAX
Returns the most positive of its arguments.
Syntax: max(<expression>, <expression>,...,<expression>)
3.8.22. MIN
Returns the most negative of its arguments.
Syntax: min(<expression>, <expression>,...,<expression>)
3.8.23. CONFINE
Constrains the given value to be not less than the minimum and not more than the
maximum values (if given). Confine works by reflecting the given value off the limits, so
that the confined value is a continuous function of all its inputs. The graph of
CONFINE(x, upper, lower) vs x is a triangle wave; that of CONFINE(x,,lower), a V shape;
and that of CONFINE(x,upper) an upside-down V shape.
Syntax: confine(x, upper)
confine(x, , lower)
confine(x, upper, lower)
3.8.24. MINIMIZE
Finds the value of x at which user function f(x) is minimized, within the limits xlo ≤ x ≤
xhi. Currently just a stub.
Syntax: MINIMIZE(f,xlo, xhi)
3.8.25. POW
Computes arg1
arg2
. No error checking is performed for raising 0 to a negative
power or a negative number to a fractional power.
Syntax: Pow(<expression>,<exponent_expression>)
