its a matlab question, Thank you!

The Fibonacci series is a commonly occurring sequence in nature. It is produced by starting with the numbers 0 and 1, and every subsequent number is the sum of the two preceding numbers. So the Fibonacci sequence until the 10th Fibonacci number would be: 0,1,1,2,3,5,8,13,21,34 (10th Fibonacci number). Write a WHILE-LOOP that: 1. Takes an input from the user 2. Sums the Fibonacci series until the input number 3. Does not use the fibonaccio) function already defined in Matlab eg. if user says 3, then output should be 2 (0+1+1); or if the user says 5 then the output should be 7 (0+1+1+2+3)
