expand()

Expands the dependent data of a variable into single points by introducing an additional inner independent variable

Syntax
y = expand(x)

Arguments

Name	Description	Range	Type	Required
x	data to be expanded (dimension is larger than one and less than four)	(-∞, ∞)	integer, real, complex	yes

Examples

Given a dependent data A which has independent variables B: If A is a 1 dimensional data containing 4 points (10, 20, 30, and 40) and similarly B is made up of 4 points (1, 2, 3, and 4),
Eqn A = [10,20,30,40]
Eqn B = [1,2,3,4]
Eqn C = vs(A,B,"X")
Using expand(C) increases the dimensionality of the data by 1 where each inner dependent variable ("X") consists of 1 point.
Eqn Y = expand(C)

Notes/Equations

In addition to the application above, the expand() function can also be used to convert a matrix into an array or vector. For example, an S-parameter matrix can be converted into an array by using the equation arr=expand(S) .
