Compare two .mat files

Compare two .mat files and display the contents and difference of mat files.

Compare two mat files,

useage: matc matfile1.mat matfile2.mat

it will show three different releationship between the variables stored in mat file:

not exist, not equal, equal.

Although one can use
A = load matfile1;
B = load matfile2;
isequal(A,B)
to determine if two mat files are exactly same, it can not help one determine which variable in matfile1 is different or does not exist in matfile2.

Example:

matc aa.mat bb.mat
Source File: aa.mat --- Target File: bb.mat
--------------------------------------------------
Variable :: a || not exist
Variable :: b || equal
Variable :: c || not equal
--------------------------------------------------

Source File: bb.mat --- Target File: aa.mat
--------------------------------------------------
Variable :: ab || not exist
Variable :: b || equal
Variable :: c || not equal
--------------------------------------------------
