I have no idea. I don't know what a "term-document matrix" is. There are an infinite number of features and it totally depends on what you are looking at and what you want to find/measure/determine. Even is you narrowed down the field, such as to image processing, there are still an infinite number of features. I don't know what "MI" is, unless it's the US state of Michigan. Is it part of one of the toolboxes? You didn't list any toolboxes in the Products list below your question, so probably not, unless you forgot to. So basically I'm unable to help you at all for because of the lack of any actionable information.
