I want to be able to write functions that I can use in many programs (the way I used to do in MatLab). I much prefer the Mathematica Language and would rather use it, but I have to be able to do this.
I have tried writing my own package using what I have found in the documentation. I wrote a package that would give the properties of air at a given temperature by interpolating from some tables.
I can get it to work by using the following commands
AppendTo[$Path,"~/Documents/School/My\ Mathematica\ Packages"]
then I can use all the functions defined in the AirProperties Package that I created.
My two questions are
1.) How do I permanently add my directory to the Path so that I don't have to do the AppendTo part every time I restart Mathematica?
2.) Am I making this a harder than it has to be.? Is there a better way?
I want to be able to build a library of my own functions and packages so that I can call them later. I would also like them to be accessible so that I have quick access to them and not have to go digging through deep system folders to find them.
By the way, I am using Mathematica 188.8.131.52 on a PowerPC 32-Bit Mac running Mac OS 10.4.10
