Matrix multiplication error arising

a = 12;
b = [1;2.5;6];
c=8;
d=(1:10)';
final = a./(b.*c.*d)

not able to get why theres an error arising

[Stephen23]

These are not compatible sizes:

size(b)

ans = 1×2

3 1

size(d)

ans = 1×2

10 1

Let's ignore the scalar values a and c, which do not cause any problem.

b is a 3x1 vector.

d is a 10x1 vector.

What do you expect to be the result of b.*d? They have a different number of elements, so the operation is ill-defined.
