How can i make a function with a input parameter?

Hi everybody,

This is my script code. I want to create a function with the input parameter 2.txt - file This function should create my plot. How can i do this? Thank you for your help.

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');

set(axes1,'Color',[0.894117653369904 0.941176474094391 0.901960790157318],...
'XMinorTick','on','XScale','log');

plot(yb,xb)

hi,

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)

• 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

• 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.
