Need help Matlab script Question

Hi, I am trying to make scripts that follow this table :

Could you choose one of them and help me finding how can i manage the differents input to make changes that are automatically saved in the .mat file

Script Name

General Algorithm

AddNewEmployee

1. Display all of the ID numbers currently in use
2. Read in a new ID number
3. If the ID number read in is already in use
4. Report this fact
5. End this script
6. Else (this is a new ID number)
7. Read in:
8. Years with the company
9. Salary
10. Vacation days
11. Sick days
12. Add this new employee to the database (by appending a new row to the end of the EmployeeData matrix)Note that this command should alter, not only the EmployeeData matrix, but also the EmployeeData.mat file (i.e. it should automatically save to the MAT-file)

DeleteEmployee

1. Display all of the ID numbers currently in use
2. Read in an ID number
3. If the ID number exists, delete that employeeNote that this command should alter, not only the EmployeeData matrix, but also the EmployeeData.mat file (i.e. it should automatically save to the MAT-file)
4. Else tell the user that that employee ID does not exist

PrintEmployees

1. Print out a table showing all of the current employees and all of their respective data

ShowEmployeeDataStatistics

1. Print out statistics about the current employees including:
2. The number of employees
3. The average, minimum, and maximum values of:
4. Years at the company
5. Salary
6. Vacation days
7. Sick days

FindMaxEmployee

1. Find and report the employee ID with the maximum value of either:
2. Years at the company
3. Salary
4. Vacation days
5. Sick days

If more than one employee has that maximum value, show all of the ID numbers with that maximum

FindMinEmployee

1. Find and report the employee ID with the minimum value of either:
2. Years at the company
3. Salary
4. Vacation days
5. Sick days

If more than one employee has that minimum value, show all of the ID numbers with that minimum
