Usage

`javascript
var dladiv = require( '@stdlib/lapack-base-dladiv' );
`

#### dladiv( a, b, c, d, P, Q )

Divides two double-precision complex floating-point numbers in real arithmetic.

`javascript
var Float64Array = require( '@stdlib/array-float64' );

var P = new Float64Array( 1 );
var Q = new Float64Array( 1 );

dladiv( -13.0, -1.0, -2.0, 1.0, P, Q );
// P => [ 5.0 ]
// Q => [ 3.0 ]
`

The function has the following parameters:

- a: real component of numerator.
- b: imaginary component of numerator.
- c: real component of denominator.
- d: imaginary component of denominator.
- P: [Float64Array][mdn-float64array] containing a single element which is overwritten by the real part of the quotient.
- Q: [Float64Array][mdn-float64array] containing a single element which is overwritten by the imaginary part of the quotient.

#### dladiv.ndarray( a, b, c, d, P, offsetP, Q, offsetQ )

Divides two double-precision complex floating-point numbers in real arithmetic using alternative indexing semantics.

`javascript
var Float64Array = require( '@stdlib/array-float64' );

var P = new Float64Array( 1 );
var Q = new Float64Array( 1 );

dladiv.ndarray( -13.0, -1.0, -2.0, 1.0, P, 0, Q, 0 );
// P => [ 5.0 ]
// Q => [ 3.0 ]
`

The function has the following parameters:

- a: real component of numerator.
- b: imaginary component of numerator.
- c: real component of denominator.
- d: imaginary component of denominator.
- P: [Float64Array][mdn-float64array] containing an element which is overwritten by the real part of the quotient.
- offsetP: index of the element in P.
- Q: [Float64Array][mdn-float64array] containing an element which is overwritten by the imaginary part of the quotient.
- offsetQ: index of the element in Q.

While [typed array][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example,

`javascript
var Float64Array = require( '@stdlib/array-float64' );

var P = new Float64Array( [ 0.0, 0.0, 0.0 ] );
var Q = new Float64Array( [ 0.0, 0.0, 0.0 ] );

dladiv.ndarray( 2.0, 1.0, 3.0, 4.0, P, 1, Q, 2 );
// P => [ 0.0, 0.4, 0.0 ]
// Q => [ 0.0, 0.0, -0.2 ]
