I need help with the MATLAB code

Solution to the problem.

My incorrect code:

% Gravity g=9.81;

% Mass input from user Mc=input('Provide mass for C: '); Md=input('Provide mass for D: '); Ma=input('Provide mass for A: ');

% Calculation of weights: Wc = Mc * g; Wd = Md * g; Wa = Ma * g;

% As Mb=0, Reaction at A can be calculated as: A = (3.75*Wc + 2.05*Wd + 1.2*Wa)/(3*2);

% As Fy=0, Reaction at B can be calculated as: B = -(2*A-Wc-Wd-Wa)/2;

Two crates, each of mass 350 kg, are placed as shown in the bed of a 1400-kg pickup truck. Determine the reactions at each of the two (a) rear wheels A, (b) front wheels B. This time when someone uses your program they should have the option of changing the masses of the crates. 17 m 2.8 m 1.8 m 1.2 m 0.75 m Two crates, each of mass 350 kg, are placed as shown in the bed of a 1400-kg pickup truck.
