Can anyone help with this MATLAB problem??? Thank you so much!!

Write a function called rom2num that converts Roman numerals to numbers. Recall characters in Roman numerals are

numeral	number
I	1
V	5
X	10
L	50
C	100
D	500
M	1000

The input is a valid Roman numeral entered as a string. The output is a number. For example, rom2num(VII) yields 7.

There are many approaches. See section 9.2 of van Loan for an approach. We will discuss section 9.2 in lecture 5. A simpler approach is the following.

Write a function called Converter that takes the strings I,V,X,L,C,D,M and returns the corresponding numbers. Use the switch case construction for the different possibilities.

Set S=0.

Read the characters from left to right

At each step call the function Converter. Add the corresponding value to S.

At each step check the value of the previous character. If it is less, then subtract two times that value from S.
