Re: Defining a function in module problem?

May it be, that Evaluates should get a general expression - a function to evaluate it? You set a symbol z/3 to a symbol g, whereas the single parameter z in Function construct is not this same symbol z, but is treated as a local variable.


Correction:

g[z_]:=z/3;
f=Function[z,Evaluate[g[z]]];



Bye,

Borut
