I have a code which was given by image analyser

H = figure;
for ii = 321:326
  subplot(ii)
  imagesc(magic(ceil(rand*10))); %random fig with 6 subplots
end
print('-dbmp256' , 'picture_of_6_subplots') %save as bmp

i want it to be saved in a folder named 'new',because i will have 100 figure windows,in which each figure window contains 8 subplotted images

Maybe you are seeking for this sample code :

clear; clc;
I = imread('peppers.png');
J = imread('onion.png');
K = imread('pears.png');
Img = {I J K};
for cnt1 = 1 : length(Img)
    figure,    
    subplot(2,3,1),imshow(Img{cnt1});
    subplot(2,3,2),imshow(rgb2gray(Img{cnt1}));
    subplot(2,3,3),imshow(im2bw(Img{cnt1}));
    filename = strcat('picture_of_figure',num2str(cnt1));
    print('-dbmp256',filename);
end

Then you need to specify your path folder

Eq : filename = strcat('E:\picture_of_figure',num2str(cnt1));

In your case is :

filename = strcat(pwd,'\New\picture_of_figure',num2str(cnt1));

If you have a folder named 'New' in your active directory.

using fullfile ( folder, filename ) is better than strcat.
