A = rand(3,3,18) ;
[m,n,p] = size(A) ;
B = zeros(m,n,p) ;
for i = 1:p
B(:,:,i) = inv(A(:,:,i)) ;
end

If you're using release R2022a or later you could use the pageinv function. But if you're planning to invert these matrices in order to multiply them by something else to solve a system of equations, I would advise you to use pagemldivide (also release R2022a) instead of using both pageinv and pagemtimes (release R2020b.)
