You can use mat2cell to divide up the matrix into the submatrices. This will give you a cell array of submatrices.

But what does "store in notepad" mean? Notepad is a simple text editor for Microsoft Windows, but it is not a data storage standard. If you actually meant "text file" , then consider using dlmwrite to write each matrix in the cell array to a text file. If this is not what you meant by "store in notepad", then you will need to explain what you want to do.

And please read the documentation as it actually explains how to use these functions and gives examples too!
