A new version of the Attribute Extraction program for the Experimental Dynamic Processor is described. This new version takes advantage of the drum storage and display capability of the DIGIGRAPHIC equipment that has been added to the DX-1. The several display programs and the Attribute program have been compatible and work under a common executive routine, the DEXTER system. The order of solvable matrices has been increased from 50 to 160. Some preliminary results are given. The special display programs are described. The Power Method to find eigenvalues and eigenvectors of large matrices is described. A simulation of a proposed optical eigenvalue and eigenvector processor is described. (Author).
