I need to keep track of a list of variables and their parameters, for example one variable might be 'Students' and the parameters might be 'Grades', 'Absences', and 'Age' . Another variable might be 'Teachers' and the parameters might be 'Salary' and 'Classes'. What is the best way to keep track of these strings? Create a cell array? I do not need to assign values at the present, I just want to keep track of which parameters go with which variables.

This seems to be what classes are perfect for.
classdef students
properties
Grades;
Absences;

I would use a struct
Students = struct('Grades',{'A';'B'},'Absences',[4;11])
etc.
doc struct

You may want to check out structures or datasets.
Here is a blog article that goes into a little more detail.
If you use a structure, for example, you would have the variable named Students, and the fields would be Grades, Absences and Age. If you wanted to recall all the fields, just use the fieldnames function.
Both are very useful, and I think they will work for what you want. If you wanted to get more fancy, you could create your own class objects with the parameters as properties.

use dataset() or structure
Student=cell2struct(repmat({[]},3,1),{'Grades','Absense','Age'},1)
StudentProperty=fieldnames(Student)
