Write a MATLAB program to do the following steps:

Load the following MAT file:

BE$340\_$MATLABTeamAssignment$\_$secretcode$.$mat

Convert the integer values to ASCII characters using the "char" command

The $"$str$"$ array values will need to be adjusted to display the string correctly

Subtract $3$ from all values in row #$1$ and columns #$26-$#$50$

Add $10$ to all values in row #$2$ and columns #$1-$#$9$

Subtract $5$ from all values in row #$2$ and columns #$10-$#$30$

Display the new string using the "char" command
