I run a script and the error message was

">> quiver_bak(varargin)
Attempt to execute SCRIPT varargin as a function:
C:\Program Files\MATLAB\R2017b\toolbox\matlab\lang\varargin.m".

What i have to type as a function?

Do NOT use varargin outside of any function: it only works inside of a function. Call your function like this:

quiver(X,Y,...)

Where X, Y, etc are any input variables or values that the function needs.

The code you attached (a copyrighted copy of quiver) has this example, note how it does not use the term varargin anywhere:

[x,y] = meshgrid(-2:.2:2,-1:.15:1);
z = x .* exp(-x.^2 - y.^2); [px,py] = gradient(z,.2,.15);
contour(x,y,z), hold on
quiver(x,y,px,py)
