RealVector

Converts an object to a real vector.

Syntax

If X is any object, then RealVector(X) returns X as a real vector, if possible.

Specifically,

If X is a real number, not of datatype complex number, then RealVector(X) returns the one-dimensional vector with single component X. To force a possibly complex number with zero imaginary part into a one-dimensional real vector, you must write RealVector(RealNumber(X)).
If X is of type complex number (even if its imaginary part is zero), then RealVector(X) returns the two-dimensional vector ❨Re(X), Im(X)❩.
If X is a real vector or a complex vector with zero imaginary part, then RealVector(X) returns X as a real vector.
If X is a real matrix or a complex matrix with zero imaginary part, then RealVector(X) returns the real vector containing the entries of X in row-major order.
If X is a list of numbers with zero imaginary parts, then RealVector(X) returns the real vector containing these numbers. If the list contains any non-numbers, they are ignored.
If X is a set of numbers with zero imaginary parts, then RealVector(X) returns a real vector containing these numbers in undefined order. If the set contains any non-numbers, they are ignored.
If X is a structure containing numbers with zero imaginary parts, then RealVector(X) returns the real vector containing these numbers. Any non-numbers in X are ignored.
If X is a string, it is split on comma, semicolon, tab, and linebreaks, in an attempt to parse it as a real vector.
