I have a code that has to calculate the amount of ballast needed to be added to move the center of mass to the center geometry and where it should be added(Its position)
I made a for loop with the added mass as the index. This gives multiple Positions but i need to get the FIRST to satisfy my required conditions
My code is as follows...
I want the first Positive Pos_add that is Less or equal to DesiredCoM. Instead of all the Pos_adds that meet this condition...(which it gives me)
for M_add=1:0.01:Mass;
Pos_add=(-sum(Masses.*Positions)+(DesiredCoM)*(Mass+M_add))/M_add
if Pos_add>0 & Pos_add<=DesiredCoM
break
end
endfor

% Find the position of the first element that matches.
pos = find(Pos_add > 0 && Pos_add <= DesiredCoM, 1, 'first');
% Get the value
answer = Pos_add(pos);
