Write a function Divide that divides two numbers, and keep count of how many times the function was called asking to divide by zero. The function has two output, the division of the two numbers and the number of times the function was called with a divide-by-zero request. In the case of a divide-by-zero request, the resultant should be set to not a number. The function must make use of a persistant variable. For example >> clear all; x=1; y=1; [z,times] Divide (x,y) = 1 times = >> x=1; y=0; [z,times] Divide(x,y) = NaN times = 1 [z,times] = Divide(x,y) >> x-2; howmany y=0; 2 NaN times = 2 Your Function Save Reset , MATLAB Documentation
