regress    

extracts the regressors from the data

Syntax

Description

[r_in,r_out]=get_regressors(m) extracts the regressors from the model m, for all the outputs of the system.

[r_in,r_out]=get_regressors(m,j) extracts the regressors from the model m, for all the outputs of the system defined in the array j.

Remarks

This function uses the dynamical system representation stored in the 'dynamics' field to extract the regressors form the input-output data stored in the 'data' field. The function returns the input regressors r_in in a cell array. Each element of the cell array is a regressor associated with an output. Each regressor is an array of size size_regressor * num_exaples, where size_regressor depends from the structure of the regressor defined in the dynamical description of the system, and num_exaples is the number of exaples given in the input-output data set. r_in is a cell array returing the corrispondent output of each regressor taken from the output data set. Each entry in the cell array is a vector of size 1 * num_exaples.
