Hi I want to write a function with one input parameter and no output parameters. How do I access the input parameter in its base worksapce in order to manipulate it?

Please provide the code so we can have a better idea of what your are doing.

You have to start with the base workspace. For example, you have par=1 in base workspace. Then you call your function Process(par).
Your function might look like:
function Process(Var)
VarName=inputname(1);
assignin('base',VarName,Var+rand);
However, this is not recommended because you are manipulate variables across boundary or scope. You can always do it this way, assume initially par=1 in base workspace
par=Process(par);
Where your Process() function looks like:
function out=Process(par)
out=par+rand;

@Stagleton, that could work. But you could also do as below if you define the output argument of your function. That is more safer and follow a good programming practice regarding variable scope.
r=1;
r=inc(r);
