The way to do this is to start creating the inverse of your matrix (decryption matrix). After we find this inverse (say mxm), we will multiply this by another matrix (1xm). We will continue to multiply the original matrix by as many types of 1xm matrices depending on the length of the code. From the results we have, we will discover the code. We also have a scale that translates the numbers into letters. For example 0=space, 1= a, 2=b.....
