Test whether two double-precision complex floating-point numbers are not equal.
npm install @stdlib/complex-float64-base-assert-is-not-equalWe 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!

#### stdlib_base_complex128_is_not_equal( z1, z2 )
Tests whether double-precision complex floating-point numbers are not equal.
`c
#include "stdlib/complex/float64/ctor.h"
#include
stdlib_complex128_t z1 = stdlib_complex128( 5.0, 2.0 );
stdlib_complex128_t z2 = stdlib_complex128( 5.0, -2.0 );
bool v = stdlib_base_complex128_is_not_equal( z1, z2 );
`
The function accepts the following arguments:
- z1: [in] stdlib_complex128_t first double-precision complex floating-point number.[in] stdlib_complex128_t
- z2: second double-precision complex floating-point number.
