Write a output code line at the end of the script using fprintf to appropriately display c, d, e, and f and their values. How would you modify the code using if/elseif combination and obtain the same result. Explain how the modification changes the program execution.

Solution

The number of 2\'s in the matrix is stored in c and the number of values greater than 8 is stored in d. So c will be 3 and d will be 2.

e = 6 and f = 1.5

The line for printing is

Changing to elseif:

if a(i,j)==2

c = c+1;

elseif a(i,j)>=8

d = d+1

end
