cacheFucntion.m

Function which caches the output of other functions.

Imagine you have a long-running function:

[out1,out2,out3,...] = longRunning(arg1,arg2,arg3,...)

and this function is being run many times with the same inputs. If you change this to:

[out1,out2,out3,...] = cacheFunction(@longRunning,arg1,arg2,arg3,...)

then only the first instance will run long, further calls will be grabbed from a global variable 'functionCache'. This only recaculates results when the inputs change.

Thanks to Christopher Wipf for most of the code.
