How can i write input variables from a text file into my script

The text file contaions the following variables. I have tried various ways, which are mentioned before but they don't seem to work. I would appriciate if someone could help. Thank you!

n = 3;                          
m = [120 30 30]';               
k = [6000 1500 1500]';          
d = [150 0 0]';                 
m_con = {[1,2,3],2,3};          
md_con = {[1,2,3],2,3};         
k_con = {1;[1,2];[1,3]};        
d_con = {1;[1,2];[1,3]};            
q0=[1 -1 0.5];                  
v0=[0 0 0];                     
ti = 0;                         
tf = 5;

It looks like you can simply use run to run this code as a script.

I would encourage you to rethink this strategy for loading parameters, as running a user-input text file is asking for trouble.

The reason i wanted to use user-input text is, that i want to be able to run the program for different variables simultaniously, without changing the script but it looks very difficult as you have said.

Why not use a function instead? You can put your parameters in a struct and let your function fill any missing parameter with a default value. You don't have to rely on files written to disk to change a set of parameters.

[Ege Arsan]

Could you maybe give an example how to do it?

This is the general idea I use in many FEX submissions. If you need a more fleshed out example (or want to see how you could extend this to handle Name,Value pairs) I encourage you to have a look there.

function z=MyFunction(x,y,options)
%one line description goes here
%
%general description goes here
%
%description of syntax options goes here

%create a struct that contains the defaults
persistent default_options
if isempty(default_options)
    default_options=struct;
    default_options.param1=1;
    default_options.param2=10;
end

%loop through the struct to replace the default parameters by the inputs
opts=default_options;fn=fieldnames(default_options);
for n=1:numel(fn)
    if isfield(options,fn{n})
        opts.(fn{n})=options.(fn{n});
    end
end

%%% actual code goes here %%%

end
