In the case of a for loop, the commands are executed a fixed number of times, whereas in a while loop the commands are executed until some specified condition is met. The paths purpose is to pick a number in the adjacent column that is closest to the current number the function i am trying to use in the loop picks this. The binopdf function expands scalar inputs to constant arrays with the same dimensions as the other inputs.
