Question

This is a question for MATLAB. Thanks for any help in advance!

The handicap differential (HCD) for a round of golf is calculated from the formula: 113 (Score Course Rating) Course Slope HCD = The course rating and the slope are measures of how difficult a particular course is. A golfer's handicap is calculated from a certain number N of their best (lowest) handicap scores according to the following table # Rounds plaved 15-16 # Rounds played N N 7-8 9-10 11-12 13-14 For example, if 13 rounds have been played, only the best five handicaps are used. A handicap cannot be computed for fewer than five rounds. If more than 20 rounds have been played, only the 20 most recent results are used. Once the lowest N handicap differentials have been identified, they are averaged and then rounded down to the nearest tenth. The result is the player's handicap. Write a program in a script file that calculates a person's handicap The program asks rating, the second is the course slope, and the third is the players score. Each row corresponds to one round. Th the user to enter the golfers record in a three columns matrix where the first column is the course program for players with the f ollowing records. e program displays the person's handicap.

Explanation / Answer

The HCD formula is given as:

HCD = 113(score - course rating) / course slope

MATLAB CODE:

rounds=input('Enter No of rounds');
for i=1:rounds
Crating(i)=input('Enter Course Rating:');
Cslope(i)=input('Enter Course Slope:');
Cscore(i)=input('Enter Course Score:');
end
if(rounds==5||rounds==6)
N=1
elseif(rounds==7||rounds==8)
N=2
elseif(rounds==9||rounds==10)
N=3
elseif(rounds==11||rounds==12)
N=4
elseif(rounds==13||rounds==14)
N=5
elseif(rounds==15||rounds==16)
N=6
elseif(rounds==17)
N=7
elseif(rounds==18)
N=8
elseif(rounds==19)
N=9
elseif(rounds==20)
N=10
end
sumRating=0;
sumSlope=0;
sumScore=0;
for i=1:rounds
sumRating=sumRating+Crating(i);
sumSlope=sumSlope+Cslope(i);
sumScore=sumScore+Cscore(i);
end
avgRating=(((sumRating/rounds)+5)*10)/10;
avgSlope=(((sumSlope/rounds)+5)*10)/10;
avgScore=(((sumScore/rounds)+5)*10)/10;
HDC=((avgScore-avgRating)/avgSlope)*113
