How can I fix error "matrix dimensions must agree" in this code?

pd=makedist('normal', 'mu', 4.5, 'sigma', 1.25);
rang(1)
h=random(pd, 601,1);
b=5;
c:0.05;
S=1000;
betas=0.5;
betao=0.7;
y=linspace(0, 60, 100);
x=linspace(0, 60, 102);
[X,Y]=meshgrid(x,y);
Z=(sum((S-X+min(b*(max(0,h-6)),Y)-b*(max(0,h-6))).^(1-betao))/(1-betao))/lenght(h)...
+(0.7*sum(((X-(c\2)*6^2-min(b*(max(0,h-6)),Y)).^(1-betas))/(1-betas))/lenght(h)));
[X,Y,Z]=peaks;
contour(X,Y,Z,20)

@Walter Roberson, thank you very much for taking time to comment on this. As you mention in your post, by sizing the min at 100 x 100 and the max at 100 x 1 would solve the error "Matrix dimensions agree". Then a second error appears in relation to the size of Z "Z must be a matrix, not a scalar or vector". That can be solved by taking the non-random parameters outside the integral. This allows me to create a 3D plot with surf.
min(b*(max(0,h-6)),Y)
The above line shows error. The dimensions of input to min re different.
