Cada vez que corró este código obtengo este error Error using plot Vectors must be the same length., he intentado de todo pero no sé cuál es el problema.

L=1.2;
l=0:0.175:0.8;
W=200;
a=1;
w=W/a^2*l;
DX=0.0001;
%%
for l = 0.1:0.175:0.8
    w=(W/((a^2)*l))*a;
    B_y=((w*a)*(L/2)*0.4)/0.8;
    A_y=((w*a)*(L/2))-B_y;
    
end
%%
for l = 0:0.175:0.8
    x1= 0:DX:(((0.8-l)/2)+0.2);
    n1= length(x1);
    x2= (((0.8-l)/2)+0.2):DX:(0.6+(l/2));
    n2= length(x2);
    x3= (0.6+(l/2)):DX:(1.2);
    n3= length(x3);
   V1= A_y; 
   M1= A_y*(x1-0.2);
   V2=A_y-(w*a*(x2-0.6));
   M2=A_y*(x2-0.2)-(w*a((x2-0.6).^2)/2);
    
   V3= A_y+B_y-(w*a*(x3-0.6));
   M3= A_y*(x3-0.2)+B_y*(x3-1)-(w*a*((x3-0.6).^2)/2);
%%grafica son los limites

You need to rethink on your code...you have messed up at lot of places...What exactly you are trying to plot?

I need to plot the V vs m, that's my force vs distance, but I have 5 different plots because I have a variable with 5 different inputs or values. But, I don't what it's happening with my code, and what i messed up.

I would appreciate it if you would help me to know what I did wrong and how I could correct it.
