It means that you have written a script errorbar. Scripts never accepts or return argument.... And you are calling this script with 3 arguments.

Instead of writing your code as script create a function which accepts arguments.
In your file errorbar.m
function errorbar(In1, In2, In3)
% Your Code
end

my command is:
>> x=linspace(0.2,21);
>> y=erf(x);
>> e=rand(size(x))/10;
>> errorbar(x,y,e)
and immediately stated:
??? Attempt to execute SCRIPT errorbar as a function:

Did you edit your C:\Documents and Settings\Albert\errorbar.m to start (very first line) with "function" ?
