Using MATLAB, how do you plot vectors and the resultant force?

It starts with an importanted excel sheet. First column in excel is the magnitude, second column is the direction.

Need to use a "FOR Loop"

This is what I have so far:

data = xlsread('Project2.xlsx');

[r,c] = size(data);

for i = 1:r arrayx(i) = data(i,1)*cosd(data(i,2)); arrayy(i) = data(i,1)*sind(data(i,2)); end

x = sum(arrayx); y = sum(arrayy);

rmag = sqrt(x^2 + y^2); rdir = atan(y/x);
