if true
A = rand(361,285);
B = reshape(A,19,19,19,15);
end

I want to display each 19*19 into an image into 19*15 subplots under one figure.

285 subplots in one figure? That ain't gonna be pretty.

What part of the subplot() documentation did you not understand when you read it?

Optioin 1: Using subplot

A = rand(361,285);
B = reshape(A,19,19,19,15);
%%Save each 19*19 matrix into image
for i = 1:19
    for j = 1:15
        idx = sub2ind([15,19],j,i) ;
         subplot(19,15,idx) ;
         imshow(B(:,:,i,j))
         drawnow
    end
end

Option 2: Using montage

A = rand(361,285);
B = reshape(A,19,19,19,15);
%%Save each 19*19 matrix into image
fnames = cell(1,19*15) ;
for i = 1:19
    for j = 1:15
        idx = sub2ind([15,19],j,i) ;
        fnames{idx} = strcat(num2str(idx),'.jpeg') ;
        imwrite(B(:,:,i,j),fnames{idx}) ;
    end
end
 montage(fnames, 'Size', [19, 15]);
