FTN95 + Simdem = Rapid Graphics Development

FTN95 includes ClearWin+ and that makes it easy to produce complex graphics -- Simdem makes it even easier! Simdem is a graphical library built on ClearWin+ that lets you produce complex graphs and plots in a few lines of Fortran. What is more, Simdem is free.

  • Easy - Just link in the library and away you go
  • Free - No licence required to use the library
  • Source Code - You can build the library yourself if you want to.
  • Examples - Simdem comes with a suite of examples.
  • Output - Plots can be sent to a printer or converted to Postscript.
  • Mature - Simfit is based on the same source code.

Below are just a few examples of output generated by SIMDEM using ClearWin+ and FTN95. There are more here.
