Plot function 'createfigure' - auto generated - has an unknown matrix input

Hello community,

i do have a plot function which was auto generated by matlab. I did the work on the graph interactively and then wanted to generate the code and implement it in the existing one, because I have a lot of graphs who should look the same.

In this figure i want to plot 3 graphs (2 stem, 1 plot) with 2 y-axes. The generated code shows the following:

if true
  % function createfigure1(X1, ymatrix1, Y1)
     %CREATEFIGURE1(X1,YMATRIX1,Y1)
    %  X1:  stem x
    %  YMATRIX1:  stem matrix data
    %  Y1:  vector of y data
    %  Auto-generated by MATLAB on 22-Oct-2012 15:37:26
    % ....
    % Create figure  end

What is "YMATRIX1: stem matrix data"? I do not want a matrix to be shown in the figure.

Thanky,
