How can I power the elements of a 3D matrix to the elements of 2D matrix?

Dear All, I have two cells arrays which contains matrices. In one of the cell array are 3D matrices and in the other one are 2D matrices. I would like to power the elements of 3D matrices to the elements of 2D matrices. I tried to solve by the following code:

for jj=1:360;
    bb=B{jj};
    for kk=2:360;
        m=out_m{kk};
        for i=1:464;
            for j=1:201;
                for k=1:size(m,3);
                    P(i,j,k)=m(i,j,k).^bb(i,j);
                    PP{jj,1}=P;
                end
            end
        end
    end
end

It is very slow. Could someone suggest me a better method?

a=randi(10,4,3,2)
b=randi(10,4,3)
out=bsxfun(@power,a,b)

Let you data is arrays B and out_m :

B={};
out_m = {};
for jj = 1:3
    out_m{jj} = randi(6,2,3,4); 
    B{jj} = randi(5,2,3);
end

solution:

bb = cat(4,B{:});
m = cat(4,out_m{:});
P = bsxfun(@power,m,bb);
PP = reshape(num2cell(P,[1 2 3]),[],1);
