3d Functions

Functions of two variables are difficult to reproduce on paper because they exist in 3-D space. 3-D Functions supplies the user with different functions to choose from, to add or multiply or divide up to 10 function combinations into a special function. Also supplied is a bunch of preset functions and one nested function. Version 2 adds the option of contour plots and constraint functions that can be used in optimization problems, where the user has to identify the region where the function is at an minimum value, etc... Version 2.2 added the feature of producing a quicktime movie of a rotating surface. The current plot position is rotated 360 degrees about the z-axis in one degree increments. The demo is limited to a preset function. The full version can assemble multiple functions (see documentation). This demo can be distributed freely and may be included on the archive's CD ROM. -- Hussam Dandashli Software Engineer http://www.skyenet.net/~hussamd/index.html email: hussamd@skyenet.net 319 Gage Ave Elkhart, IN 46516 U.S.A
