logical-and#

Purpose#

Performs logical AND operation.

y = a and b

param a:

Left operand.

type a:

scalar

param b:

Right operand.

type b:

scalar

return y:

1 if both a and b are non-zero, 0 otherwise.

rtype y:

scalar

y = 1 and 1;

y =    1.0000000

y = 1 and 0;

y =    0.0000000

y = 0 and 0;

y =    0.0000000

x = 5;
if (x > 0) and (x < 10);
    print "x is between 0 and 10";
endif;

x is between 0 and 10

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