You need to call uiputfile() before calling imwrite().

Read the documentation.
http://www.mathworks.com/access/helpdesk/help/techdoc/ref/uiputfile.html
and look in the Example section.

Once you have a filename and pathname returned from uiputfile, and you
have checked in case the user requested to cancel the operation, then
use fullfilename() to create a complete file name and pass that to
imwrite() in place of a quoted string.
