I want to run a list of distance values through these two formulas for force and combine them into one 1x3 matrix in the form [dist force1 force2].]

clear;

clc

mmass=input('What is the mass of the main object?');

sat1=input('What is the mass of the first satellite?');

sat2=input('What is the mass of the second satellite?');

for DistVector = 200e6:10e6:100e7;

Force1=(mmass*(sat1^2))/(DistVector.^2);

Force2=(mmass*(sat2^2))/(DistVector.^2);

your_matrix = [DistVector(:), Force1(:), Force2(:)]

end

You shouldn't need to use a loop for that. MATLAB can calculate the formulas directly as vectors for all of the points in DistVector. Then just concatenate the results columnwise in your output array

So something like this. You can check the formulas to make sure they are correct. I removed a bunch of unneeded parentheses, and also note the ./ for element by element division of the scalar numerator and the vector denominator

mmass = 10;
sat1 = 5;
sat2 = 3;
DistVector = 200e6:10e6:100e7
Force1=mmass*sat1^2 ./DistVector.^2;
Force2=mmass*sat2^2 ./DistVector.^2;
your_matrix = [DistVector(:), Force1(:), Force2(:)]

It looks like you are calculating the gravitational attraction between a satellite and main mass. If so, I wonder if your formula is correct. Shouldn't it just be proportional to m1*m2/d^2 ? You have m1*m2^2/d^2, so you have units of mass cubed in the numerator. Also shouldn't there be a constant of proportionality, G, in there?
