Exercise 9: Dynamic Field Names Example. The avgscore function shown below computes an average test score, retrieving information from the testscores structure using dynamic field names: - Create the following function: function avg= avgscore (tests cores, for k first: last student, first, last) scores (k) testscores. (student) week (k) avg = sum (scores)/ (last - first + 1); end -Create the following structure: testscores.Ann Lane.week (1:25) - testscores.William King. week (1:25) - [95 89 76 8279 92 94 92 89 81 75 93.. . 85 84 83 86 85 90 82 82 84 79 96 88 981; [87 80 91 84 99 87 93 87 97 87 82 89... 86 82 90 98 75 79 92 84 90 93 84 78 811 -Now run avgscore,supplying the students name fields for the testscores structure at runtime using dynamic field names: avgscore (testscores,'Ann Lane', 7, 22)
