add

Add two single-precision complex floating-point numbers.

Usage

var add = require( '@stdlib/complex/float32/base/add' );

add( z1, z2 )

Adds two single-precision complex floating-point numbers.

var Complex64 = require( '@stdlib/complex/float32/ctor' );
var realf = require( '@stdlib/complex/float32/real' );
var imagf = require( '@stdlib/complex/float32/imag' );

var z = new Complex64( -1.5, 2.5 );

var v = add( z, z );
// returns <Complex64>

var re = realf( v );
// returns -3.0

var im = imagf( v );
// returns 5.0

Examples

var Complex64 = require( '@stdlib/complex/float32/ctor' );
var discreteUniform = require( '@stdlib/random/base/discrete-uniform' ).factory;
var add = require( '@stdlib/complex/float32/base/add' );

var rand = discreteUniform( -50, 50 );

var z1;
var z2;
var z3;
var i;
for ( i = 0; i < 100; i++ ) {
    z1 = new Complex64( rand(), rand() );
    z2 = new Complex64( rand(), rand() );
    z3 = add( z1, z2 );
    console.log( '(%s) + (%s) = %s', z1.toString(), z2.toString(), z3.toString() );
}

C APIs

Usage

#include "stdlib/complex/float32/base/add.h"

stdlib_base_complex64_add( z1, z2 )

Adds two single-precision complex floating-point numbers.

#include "stdlib/complex/float32/ctor.h"
#include "stdlib/complex/float32/real.h"
#include "stdlib/complex/float32/imag.h"

stdlib_complex64_t z = stdlib_complex64( 3.0f, -2.0f );

stdlib_complex64_t out = stdlib_base_complex64_add( z, z );

float re = stdlib_complex64_real( out );
// returns 6.0f

float im = stdlib_complex64_imag( out );
// returns -4.0f

The function accepts the following arguments:

z1: [in] stdlib_complex64_t input value.
z2: [in] stdlib_complex64_t input value.

stdlib_complex64_t stdlib_base_complex64_add( const stdlib_complex64_t z1, const stdlib_complex64_t z2 );
