I want to collect the smallest arrays on the 3rd axis and get a 2d image.

i have a 3X3X3 double data
a=[1 1 1;10 10 10;10 10 10];
b=[20 20 20;2 2 2;20 20 20];
c=[30 30 30;30 30 30;3 3 3];
d=cat(3,a,b,c);
To illustrate, let's say 3X3X3 is row, column, page.
I want to find the minimum value several pages with fixed rows and columns.
I think repeating this would make one 3X3 matrix in each row and column.
I think it's possible if i use "for loops" to find it. But can't do this using "min()"?
% i want get e=[1 1 1 ;2 2 2; 3 3 3]
e=[1 1 1 ;2 2 2; 3 3 3]
