I want to clear a particular field in GUI before executing a function. I have tagged the things to be cleared. But i do not know the syntax to clear those tags.

What do you mean by field?
Do you want to clear an edit-box from its content and leave it blank?

delete(findall(gcf,'Tag','Tagname'))

You could set the 'String' property to '' so that it displays an empty string:
set(YourHandle,'String','');
or you could make it not visible:
set(YourHandle,'Visible','Off');

How did you "tag" them? The tag is the ID name of the control - you'll see if if you bring up the property inspector in GUIDE. Every control always must have a tag, though you can assign any name you want. What is your definition of tag? How did you "tag" the controls that you want cleared? And what exactly does "clear" mean? You can use clear() or delete() in your code to get rid of a control, though I think that's risky. Or you can use
set(handles.editBox1, 'String', '');
to remove any text in the edit text control with the tag name property of "editBox1".
