Iv got an image and i hv to divide its pixels into subpixels in a matrix form and then randomly assign 0 and 1 to its rows and columns.

[Image Analyst]

subpixels = randi(1, rows, columns);

where rows and columns are some number more than the rows and columns of the original image. For example

[originalRows, originalColumns, numColors] = size(grayImage);
rows = 2 * originalRows;
columns = 2 * originalColumns;
subpixelImage = randi(1, rows, columns);

Now each pixel will be "occupied" by 4 pixels of the higher resolution subpixelImage.
