To write image data into image use imwrite.

Thank you for your answer

I have used 'imwitte' but it saved one image of all images as shown in figure.

I'm looking for saving each image in figure as a spaerated image and same for other. The folder of images should have 25 images that showed in figure. BTW, all 25 images save as one matrics.

I gave you a link to refer on how to split your images into sub images.

for a matrix A with ynum images in y direction and xnum images in x direction with size height x width you can use

C = mat2cell(A,repelem(height,ynum),repelem(width,xnum));

this divides A into a bunch of cell arrays. you can then use cellfun or a ordinary double for loop with your own custom function to save each cell entry

alternatively you can use the function blockproc, to which you can give the block size (subimage size) and a custom function to save the subimages
