clear all 
clc
Input_Matrix_Woehler = textread('2.txt')
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]);
axes1 = axes('Parent',figure1);
hold(axes1,'on');
xlim(axes1,[1000 200000000]);
box(axes1,'on');

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)

optionally add help documentation to the function

     %agoodnameforyourfunction Plots data from two column text file ...
     %
     %inputs:
     %      fullfilename: char array containing the full path of the text file
