Identification of piecewise linear and homogeneous zone detection in matlab

The following Matlab project contains the source code and Matlab examples used for identification of piecewise linear and homogeneous zone detection. Project:1D signal:Identification of PieceWise Linear by multiple regression Detection of homogeneous zone using entropie Projection in the Hough space (1D) I/O Inputs: 1D signal (xe,ye) Simulated data (Figure 12); Outputs: Entropie signal (xee,yee) Line positions, position Line lengths, longueur Line slopes, pente Error of regression, e Purpose: E=0: Identification of PieceWise Linear (Figure 1) Projection in the Hough space (Figure 2,3) E=1: Identify homogeneous zone of a signal (detect also singularity or abrupt changes)(Figure 1) Projection in the 1D Hough space (Length of the line,position of the line) (Figure 2,3).
