BLAS diagonal element types.
npm install @stdlib/blas-base-diagonal-typesWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> BLAS diagonal element types.
``bash`
npm install @stdlib/blas-base-diagonal-types
`javascript`
var diagonalTypes = require( '@stdlib/blas-base-diagonal-types' );
#### diagonalTypes()
Returns a list of BLAS diagonal element types.
`javascript`
var out = diagonalTypes();
// e.g., returns [ 'non-unit', 'unit' ]
The output array contains the following types:
- non-unit: elements along a diagonal are not all equal to one.unit
- : elements along a diagonal are all equal to one.
`javascript
var contains = require( '@stdlib/array-base-assert-contains' ).factory;
var diagonalTypes = require( '@stdlib/blas-base-diagonal-types' );
var isDiagonalType = contains( diagonalTypes() );
var bool = isDiagonalType( 'non-unit' );
// returns true
bool = isDiagonalType( 'unit' );
// returns true
bool = isDiagonalType( 'beep' );
// returns false
`

#### STDLIB_BLAS_DIAGONAL_TYPE
An enumeration of BLAS diagonal element types with the following fields:
- STDLIB_BLAS_NON_UNIT_DIAGONAL: elements along a diagonal are not all equal to one.
- STDLIB_BLAS_UNIT_DIAGONAL: elements along a diagonal are all equal to one.
`c
#include "stdlib/blas/base/diagonal_types.h"
const enum STDLIB_BLAS_DIAGONAL_TYPE v = STDLIB_BLAS_UNIT_DIAGONAL;
`
- Enumeration constants should be considered opaque values, and one should not rely on specific integer values.
