Purpose

Multilinear regression

Description

"Multilinear regression" fits a linear combination of the components of a multi-channel signal x to a single-channel signal y and returns the residual (i.e. the difference signal)

of the multilinear regression

where are the channels of the multichannel signal.
The computed coefficients and b are displayed in the message window.

Example

Use the macro LinComb.dpm to create a linear combination z of two input signals x and y. Then generate a multichannel signal s out of x and y using Merge. Applying "Multilinear regression" to s and z will recover the coefficients you used in the first step and yield a residual near 0 (the small fluctuations are due to roundoff errors).


Macro Synopsis

r = MultiLinRegress([x,y]);
signal r,x,y;

Note that x is a multi-channel signal.
