x1 = Input_Matrix_Woehler(:,1)
y1 = Input_Matrix_Woehler(:,2)
[xb,yb] = stairs(x1,y1);
figure1 = figure('Name','Woehler',...
'Color',[0.756862759590149 0.866666674613953 0.776470601558685]);

if you want to create a function, kindly check help/documentation once.

All you need to convert your script into a function is:
  • delete the clear all and clc. These have no place in a function
  • replace it with the function declaration, something like
function agoodnameforyourfunction(fullfilename)
%agoodnameforyourfunction Plots data from two column text file ...
% fullfilename: char array containing the full path of the text file
  • replace the hardcoded string in the textread call by the input variable name
Input_Matrix_Woehler = textread(fullfilename);
  • put an end at the end of the file.
