4-31 Another Example of a while Loop Write a script file to determine how many terms are required for the sum of the series 5k 2 – 2k, k = 1, 2, 3, … to exceed 10,000. What is the sum for this many terms total = 0;k = 0; while total < 1e+4 k = k + 1; total = 5*k^2 - 2*k + total; end disp(’The number of terms is:’) disp(k) disp(’The sum is:’) disp(total) The sum is 10,203 after 18 terms.

The switch Structure The switch structure provides an alternative to using the if, elseif, and else commands. Anything programmed using switch can also be programmed using if structures. However, for some applications the switch structure is more readable than code using the if structure. switch input expression % which can be a scalar or string case value1 statement group 1 case value2 statement group 2 . . . otherwise statement group n end 4-32 Z.R.K
