I am trying to find resultant force through inputs of magnitude and direction, I am first required to input how many data sets 1-10. I can get my program to repeat but whatever is the last input for both my magnitude and direction just overwrites the other inputs I had just put in for them. How do I make it so that each inut pair of magnitude and direction can be used to find their own corresponding resultant force?

I want to take the inputs to find the resultant forces in the X and Y plane then calculate the total resultant force of all the total number of resultants combined

You are replacing the m and a everytime in the for loop. try this

u=menu('What is your unit system?','SI','English');
d=input('Enter Number of Data Sets 1-10');
while d<1||d>10
    disp('Error')
    d=input('Enter Number of Data Sets 1-10');
end
n=[1:1:d];
for c=1:d
m(c)=input('Enter Magnitude of Force:');
while m(c)<0||m(c)==0
    disp('Error')
    m(c)=input('Enter Magnitude of Force:');
end
a(c)=input('Enter Angle of Force:');
while a(c)<0||a(c)>360||a(c)==360
    disp('Error')
    a=input('Enter Angle of Force:');
end
end
