How do you find the principal argument?
The principal value Arg(z) of a complex number z=x+iy is normally given by Θ=arctan(yx), where y/x is the slope, and arctan converts slope to angle.
What is the principal value of an argument?
The principal value is simply what we get when we adjust the argument, if necessary, to lie between -π and π. For example, z = 2e5 i/4 = 2e-3 i/4, subtracting 2π from the argument 5π/4, and the principal value of the argument of z is -3π/4.
How do you find Z arguments?
The argument of z is arg z = θ = arctan (y x ) . Note: When calculating θ you must take account of the quadrant in which z lies – if in doubt draw an Argand diagram. The principle value of the argument is denoted by Arg z, and is the unique value of arg z such that -π < arg z ≤ π.
What is the argument of a complex number 1 i √ 3 1 I √ 3?
Hence argument of given complex is 240°.
What is the meaning of argument in mathematics?
In mathematics, an argument of a function is a value that must be provided to obtain the function’s result. It is also called an independent variable. A function of two or more variables is considered to have a domain consisting of ordered pairs or tuples of argument values.
What is the argument of 0?
The complex number has magnitude zero, but doesn’t really have an angle. The angle of a complex number is defined by where the ray through the origin and the complex number intersects the unit circle. So, the argument of zero is undefined.
What is the argument of a logarithm?
logb(y) = x And, just as the base b in an exponential is always positive and not equal to 1, so also the base b for a logarithm is always positive and not equal to 1. Whatever is inside the logarithm is called the “argument” of the log.
What is an argument in Matlab?
Define a function that accepts a variable number of input arguments using varargin . The varargin argument is a cell array that contains the function inputs, where each input is in its own cell. Support Variable Number of Outputs. Define a function that returns a variable number of output arguments using varargout .
What is an input argument?
An input argument (the argument to an input parameter) must be a value, such as an initialized variable or literal, and must not be redefined or assigned to; an output argument must be an assignable variable, but it need not be initialized, any existing value is not accessible, and must be assigned a value; and an …
What is Nargin Matlab?
nargin returns the number of function input arguments given in the call to the currently executing function. nargin( fun ) returns the number of input arguments that appear in the fun function definition. If the function includes varargin in its definition, then nargin returns the negative of the number of inputs.
What does Varargin mean in Matlab?
input variable
What is %% used for in Matlab?
Percent. The percent symbol denotes a comment; it indicates a logical end of line. Any following text is ignored. MATLAB displays the first contiguous comment lines in a M-file in response to a help command.
What does %% do in Matlab?
Two percent signs ( %% ) have a different purpose: they are used for dividing your code into sections, which can be run independently. This allows easier debugging.
What is %% used for?
Description: The percent sign is most commonly used to indicate nonexecutable text within the body of a program. This text is normally used to include comments in your code. Some functions also interpret the percent sign as a conversion specifier.
