Imaginary component of a Frequency Response Function (FRF) function.

Note: This item is deprecated and will be removed in a future release.

Syntax

y = FrfImag(vec1,vec2)

Arguments

Name

Description

vec1

A vector of the input to a system.

vec2

A vector of the output from a given system.

Output

Name

Description

y

A vector of the imaginary component of a FRF of input vec1 and output vec2.  Its length is equal to the least power of two greater than or equal to the number of elements in vec1.

Example

Given vectors input and output, a vector is created which is the imaginary component of an FRF of the two.

Syntax

y = FrfImag(input,output)

Result

y is a vector of the imaginary component of the FRF.

Comments

vec1 and vec2 are assumed to be evenly sampled. vec1 and vec2 must have the same number of elements.
