The explosion of the graphical computational capabilities of relatively inexpensive desktop computers in the past few years makes the development of such an environment both feasible and timely. The program called DsTool (pronounced dee-ess-tool) is an implementation of one such environment for the Sun UNIX workstation. It is an efficient research tool that integrates a friendly graphical user interface, data management capabilities, a rich set of numerical algorithms together with the flexibility to add more algorithms and communicate data with other programs. DsTool has been implemented for use with the X Window system from MIT with the XView toolkit and is based upon the program kaos, written by S. Kim and J. Guckenheimer.
DsTool is available by anonymous ftp from the Center for Applied Mathematics at Cornell University, cam.cornell.edu, in the pub/dstool subdirectory.
