In general, matrix algebra theory has many applications, e.g., to to Statistics and Econometrics, Image and Signal processing and many other areas. There is a new branch of analysis, called "Idempotent Analysis". It looks like that this might be interesting for you, but I am not familiar with it. The introduction to the book "Idempotent Analysis and Its Applications" gives many applications.
