logical-or#

Purpose#

Performs logical OR operation.

y = a or b

param a:

Left operand.

type a:

scalar

param b:

Right operand.

type b:

scalar

return y:

1 if either a or b (or both) is non-zero, 0 otherwise.

rtype y:

scalar

y = 0 or 0;

y =    0.0000000

y = 1 or 0;

y =    1.0000000

y = 1 or 1;

y =    1.0000000

x = -5;
if (x < 0) or (x > 100);
    print "x is out of range";
endif;

x is out of range

Operands must be scalars. For element-by-element logical operations on matrices, use .* with comparison operators or the dotor function.
Any non-zero value is considered true; zero is false.
Both operands are always evaluated (no short-circuit evaluation).
