I'm trying to take the integral with two variables being arrays and this error keeps popping up. I'm not sure if there is another way, or if im missing something. this is what i have put in the code.

syms x
h = 0.5:0.1:5.0;
b = 0.5:0.1:5.0;
dA = (h./(b.^3))*x^3
Iy = int(dA*x^2,x,0,b)
Error using symengine
Invalid argument.
Error in sym/int (line 167)
rSym = mupadmex('symobj::intdef',f.s,x.s,a.s,b.s,options);
Error in DanielleG_Assignment4_18 (line 16)
Iy = int(dA*x^2,x,0,b)

I think the upper limit of integral cannot be a matrix.
if you change
Iy = int(dA*x^2,x,0,b) %b is array
the code works
syms x
h = 0.5:0.1:5.0;
b = 0.5:0.1:5.0;
B = 2; %limit of example
dA = (h./(b.^3))*x^3
Iy = int(dA*x^2,x,0,B)
