Be clear. Are you asking about a mat file or an m-file?
A mat file is possibly not readable if a simple save was done, unless the saver was careful to use the proper option in the save. It also depends on what is in the mat file.

    '-v6'    | 5 or later   | Version 4 features plus N-dimensional arrays,

    '-v4'    | all          | Two-dimensional double, character, and
             |              | sparse arrays
An m-file is generally readable, since it is simply a text file. However, some functions may not exist in the old release. Since we don't know what type your file is or what is in it, there is no way to give a better answer.
