how come edit box joins text together even when max - min >1

Hi, i have a edit box in a gui where i want it to collect all the numbers in it, i changed the value of max to 24 when min remains 0. I'm using this code for now

userdefinedremove = str2double(get(hObject,'String'));

display(userdefinedremove)

the display is to check what value will i get, and i found that when i type 1 (press enter), type 2 (press enter) in the edit box it become 12, i want it to be 1 and 2 separable values.

Is there some thing i did wrongly?

As an aside to my answer below, you can set 'max' to anything greater than 'min' and you will get exactly the same multi-line behaviour. So while setting it to 24 is perfectly valid, don't expect any different behaviour than setting it to 2 or 1. e.g. it will not constrain that you can only have 24 lines.

Strangely the help page on uicontrol properties seems to claim 'edit'components do not use the 'max' property which seems to directly contradict the uicontrol help page which describes the behaviour you are using correctly.

This should work:

str = get(hObject,'String');
[nLines, nCols] = size( str );

result = str2double( mat2cell( str, ones(1,nLines), nCols ) )
display( result )

The problem is that str2double will concatenate your multiline string into a single string and convert it to double. You need to convert each row to double not the whole string as one.

There may be other ways of doing this, but the method above is the simplest I found after a quick play around on command line.

Hi thanks for your reply ! what i did was create a new editbbox and use the exact similar code as the one i posted earlier. The result display was [1 2] instead of 12. What I didn't do is to clear out the Edit Text in the string properties of the edit box.
