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]);
