• Function(scalar x) means that the function requires a scalar value. If
a complex value is entered, it is automatically converted to a scalar
value; complex(x,y) -> scalar(x)
• Function(complex x) means that the function requires a complex
value. If a scalar value is entered, it is automatically converted to a
complex value; scalar(x) -> complex(x, 0)
• a,b are arguments that are used in the function.
