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.

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
