MATLAB implementation for dense descriptor applied to wide baseline stereo DAISY

In these source codes we have investigated the random planar array performance in terms of the half power beam width, the gain of an array of N elements and side lobe performance. The objective was to apply these results to wireless sensor networks to first form a search beam to locate adjacent wireless sensor networks , then form a narrow high gain beam to form a communications link.
