logical-eqv

Purpose

Performs logical equivalence operation.

Format

y = a eqv b

Parameters

param a:

Left operand.

type a:

scalar

param b:

Right operand.

type b:

scalar

Returns

return y:

1 if a and b have the same logical value (both true or both false), 0 otherwise.

rtype y:

scalar

Examples

Basic Usage

y = 0 eqv 0;

y =    1.0000000

y = 1 eqv 0;

y =    0.0000000

y = 1 eqv 1;

y =    1.0000000

Remarks

• Operands must be scalars.

• Returns 1 when both operands are true (non-zero) or both are false (zero).

• eqv is the logical opposite of xor.

• a eqv b is equivalent to not (a xor b).
