[TAB]

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

See

Scripts vs. Functions

Scripts and Functions

i dont get yet what should i do.

[TAB]

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:

C:\Documents and Settings\Albert\errorbar.m
