Create a new function file and write a function NewArray = ShiftRows_ubitname( OldArray ) that shifts the rows of an arbitrary 3-row array from rows arrangement 1, 2, and 3 to the arrangement 3, 1, and 2. For example, if the OldArray is [1 1 ; 2 2 ; 3 3], the NewArray is [3 3 ; 1 1 ; 2 2]. Your function calculations must do the following: Test that the number of rows in OldArray is 3 using an if-end structure. For any number of rows other than 3, the function must throw a message 'Number of rows in the input array must be 3' and assign a value of -1 of NewArray. Otherwise, the function must shift the rows of OldArray from 123 to 321 and assign it to NewArray. No looping is required. Contain the appropriate H1 and help text lines. Test your function in the command window as >> ShiftRows_ubitname( [1 1 ; 3 3] ) >> ShiftRows_ubitname( [1 1 ; 2 2 ; 3 3] )
