Demo

Function: demo (<filename>) Evaluates Maxima expressions in <filename> and displays the results. demo pauses after evaluating each expression and continues after the user enters a carriage return. (If running in Xmaxima, demo may need to see a semicolon ; followed by a carriage return.)

demo searches the list of directories file_search_demo to find filename. If the file has the suffix dem, the suffix may be omitted. See also file_search.

demo evaluates its argument. demo returns the name of the demonstration file.

Example:

          (%i1) demo ("disol");

batching /home/wfs/maxima/share/simplification/disol.dem At the _ prompt, type ; followed by enter to get next demo

          (%i2)                      load(disol)

          _
          (%i3)           exp1 : a (e (g + f) + b (d + c))
          (%o3)               a (e (g + f) + b (d + c))

          _
          (%i4)                disolate(exp1, a, b, e)
          (%t4)                         d + c

          (%t5)                         g + f
