The Complex data type in MLDesigner contains real and imaginary components, each of them is specified as a double precision floating-point number.
The notation used to represent a complex number is a two number pair (real, imaginary) - for example, (1.3,-4.5) corresponds to the complex number 1.3 - 4.5j. Complex implements a subset of the functionality of the complex number classes in the cfront and libg++ libraries, including most of the standard arithmetic operators and a few transcendental functions.
Complex()
Create a complex number, initialized with zero (0.0, 0.0). For example:
Complex c;
Complex(double real, double imag)
Create a complex number with the value (real, imag). For example:
Complex c(1.3,-4.5);
Complex(const Complex& arg)
Create a complex number which is identical to the complex number arg. For example:
Complex c(complexSourceNumber);
The following list of arithmetic operators modify the value of the complex number. All functions return a reference to the modified complex number (*this).
Complex& operator = (const Complex& arg)
Complex& operator += (const Complex& arg)
Complex& operator -= (const Complex& arg)
Complex& operator *= (const Complex& arg)
Complex& operator /= (const Complex& arg)
Complex& operator *= (double arg)
Complex& operator /= (double arg)
These two operators return the real and imaginary parts of the complex number:
double real() const
double imag() const
The following unary and binary operators return a new complex number:
Complex operator + (const Complex& x, const Complex& y)
Complex operator - (const Complex& x, const Complex& y)
Complex operator * (const Complex& x, const Complex& y)
Complex operator * (double x, const Complex& y)
Complex operator * (const Complex& x, double y)
Complex operator / (const Complex& x, const Complex& y)
Complex operator / (const Complex& x, double y)
Complex operator - (const Complex& x)
Complex conj (const Complex& x)
Complex sin(const Complex& x)
Complex cos(const Complex& x)
Complex exp(const Complex& x)
Complex log(const Complex& x)
Complex sqrt(const Complex& x)
Complex pow(double base, const Complex& expon)
Complex pow(const Complex& base, const Complex& expon)
double abs(const Complex& x)
Return the absolute value, defined as the square root of the norm.
double arg(const Complex& x)
Return the value defined by arctan(x.imag()/x.real()).
double norm(const Complex& x)
Return the value x.real() * x.real() + x.imag() * x.imag().
double real(const Complex& x)
Return the real part of the complex number.
double imag(const Complex& x)
Return the imaginary part of the complex number.
int operator != (const Complex& x, const Complex& y)
int operator == (const Complex& x, const Complex& y)
