Simfit is a free Open Source Windows package for simulation, curve fitting, statistics, and plotting, using a library of models or user-defined equations. Simfit has been in continuous development for many years by Bill Bardsley of the University of Manchester. Although it is written for Windows, it can easily be installed and used on Linux machines via WINE.
Simfit is developed using Silverfrost Limited's FTN95 Fortran Compiler and is currently featured on their website as a showcased application. The graphical functionality in Simfit has been released as a Fortran library called Simdem which allows the programmer to produce charts and graphs with just a few lines of Fortran. A version of Simdem is shipped with the Windows version of the NAG Fortran Builder.
A Spanish-language version of Simfit is maintained by a team in Salamanca.
I've been to the preacher I've been to the church
I gave my confession but I still feel the hurt
I've got to testify for what this woman's done to me
Some Voodoo got me so into you
I'm on pins and needles can you fel it too
Got the jones and I don't know what to do
So into you
I went to the doctor to try and find a cure
She looked into my soul said it's already been sold
And had me runnin' straight for the door
I've come to realize what this woman's done to me
Some Voodoo got me so into you
I'm on pins and needles can you fel it too
Got the jones and I don't know what to do
So into you
I've been tryin to fight it afraid I could learn to like
I've been prayin' to heaven and runnin' from hell
Some Voodoo got me so into you
I'm on pins and needles can you fel it too
Got the jones and I don't know what to do
