How to generate a binary executable file for my matlab functions so that other users can just compile this binary file and use it without looking at matlab code?

Hi, I got a question here. I wrote a function in matlab. This function needs multiple inputs. Inside the function, it also to read two .txt files for parameterization. I am trying to compile this function and these two parameter files into one binary file, so for others who want to use this function, they only need to upload this binary file into their matlab library, and then compile it and use it, without looking at the original code. Does anybody have any idea about how to do this? Thank you very much! Here is some code about my function:
%input data array: sst, Rrs412, Rrs443, Rrs488,Rrs55, Rrs667
%output data array:SSS
%function begins
function SSS...
= sss_MODIS_aNN(sst,Rrs412,Rrs443,Rrs488,Rrs555,Rrs667,I)
%import parameter files (totally there are 4 files)
Bias_In_I=importdata('b1_br_gom.mat');
Bias_Out_I=importdata('b2_br_gom.mat');
Weight_In_I=importdata('matlab_nn/w1_br_gom.mat');
Weight_Out_I=importdata('w2_br_gom.mat');
%make the input data array ready
Input_I=[nsst,nRrs412,nRrs443,nRrs488,nRrs555,nRrs667]';
%now calculate the output
n_I=Weight_In_I*Input_I+Bias_In_I*ones(1,length(Input_I(1,:)));
activation_function_I=2./(1+exp(-2.*n_I))-1;
output_I=Weight_Out_I*activation_function_I+Bias_Out_I*ones(1,length(Input_I(1,:)));
out_I_a=(Sigma_Out_I(1)*(output_I)+Mean_Out_I(1));
SSS=out_I_a(1,:);
%output has been derived

MATLAB Compiler SDK can compile into a routine that can be called from MATLAB.
Is there a particular reason that you are using importdata() with a .mat file instead of using load() ?
I recommend that you put in statements to test that the mat files are present and that the data import succeeds.
The routine does not seem to be very complicated; is there a reason to hide the code?
If the idea is not hiding the code, and is instead just bundling everything together, perhaps all you need is to Package an App

Hi, anyone can help me? I came across two questions here, with the "Package an App", I notice that it says the main file should have no input, while my main file, which is the function above, do have input. Anybody can help me clarify this? Currently I am waiting to get the license for the 'Package an App' for my Matlab.
Also, I want to know that, after I package all the files, and get the installing files, does that mean I can use the command line to run my program? Or it is just a GUI window. For people who want to use loop to process data using my function, it would be not feasible by using a GUI window. Actually, what I want is to compile my function and the parameter files into one executable file, and anyone can use this executable file under the command line. Thanks!

If I understand correctly, MATLAB Compiler SDK will add the .mat files to the project and compile them in. I could be wrong on that point as I do not read as much about Compiler SDK. (I do not have the product myself.)
Your arrays appear to be numeric. Have you considered using save -ASCII or using mat2str() to write the numeric arrays into .m files that you can then "call" to initialize your data. You can be sure that the library that was built would include the data then.
For that matter, you could use mat2str() etc. to create one single .m file that you could then hand to your users.
