What is the easiest way to embed a text data file into a .m function so that you don't need two files.

I have a function that uses a pre-generated lookup table that is stored as a text file. I would like to embed the text file into the .m file so that I don't have to move both files around.

Load your text file into a variable, however you normally read it in your code, for example:
lookuptable = fileread(yourtextfile);
Then right click on the variable in the variable browser, select 'Save As...' and in the 'Save as type' dropdown change the type from mat file to m file to let matlab autogenerate the code to create that variable.

Go into matlab preferences and under Workspace increase the Maximum array size threshold to something larger that the size of your variable. Above that threshold matlab indeed resort to saving the variable into a mat file for efficiency / readability.

I guess you can store your data as part of the code. Your may create an inner function or a subfunctions that initializes your lookup table; you can also store your data as properties of a class.

I am trying to avoid having to write a function that reformats the text (300 lines long) into MATLAB code that can be pasted into an m-file. Really just trying to get around having to cart around an extra file to make the m-file work.
