Question

I wrote a code to replicate the image to the right but for some reason the M3 and the M2 are on opposite sides and the M1 is completely wrong. Please help me fix this

clc clear all %Given: M1 = 3; G = 1.4; tot = 180; Theta= zeros(1,tot); p2_p1= zeros(1,tot); n=1; for i = 1 : 0....

On line 53: error = abs(-15 - Theta(i)); . I'm getting an error that says, "Index exceeds the number of array elements. Index must not exceed 17901". what am I doing wrong?
