IN MATLAB SOFTWARE Create the following row vectors S and R. S = 1 3 4 7 11 R = 10 1 9 -8 17 Create another vector called sqrDiff that contains the square root of the difference of S minus R corresponding elements. However, if roots result in imaginary numbers, replace those numbers with NaRN which stands for Not a Real Number. Note that NaRN is not a constant in MATLAB. The expected output of this task is: sqrDiff = NaRN 1.4142 NaRN 3.8729 NaRN
Write a C++ program that can delete an element from an array. The user nominates the values to save in the array (as in Assignment 1). The element that has to be removed from the array (nth element) is also provided by the user. The program must ensure that the value for n is valid. After the value has been deleted, the array must be displayed to the user again. Tip: To erase an element, the elements are moved to overwrite the nth element. Note that the array can now save one more position than there are elements. The number of "active" elements in the array must be updated every time.
