Is there any way to include comments (or similar) in a '.mat' file to indicate what the stored variables are?

Another option might be to use a structure:
A.values = [21 22 35]
A.label = 'temperature'
A.unit = 'degrees Celsius'
A.comment = 'measured with Pete''s device'

You can get those information. Look at this example
a=1;
b=2;
c=3;
save filename a b c
clear;
load filename
whos -file filename.mat
%or
data=load('filename')
var_names=fields(data)

Thank you, Azzi. I should have been clearer in my original question. I not only want to know the names of the variables but also some descriptive information about the variables, eg. how the data was collected, what the variables represent, etc...something similar to comments that may be used in '.m' files.

Save with your data a string that contains your informations
a=1;
b=2;
c=3;
infos={'a is ' ; 'b is ' ;'c is ';' other infos' }
save filename a b c infos

You can also create a function for each file you want to load
function filename
% comment1
% comment2
% .....
load filename
To load the file filename just type
filename
To see the comments type
help filename

Sure, create a string describing everything, save that string variable.
