Problem with ''if''

Hi everyone, I have this variable:

values =

    []    [1x27 char]    [1x32 char]    [1x28 char]    [1x34 char]

and i want have a check for empty cells. I use :

if values[ ]==[ ]

....

end

But unfortunately....

??? Conversion to logical from cell is not possible. What can i do???

Answer 1

[Robert Cumming]

cellfun ( @isempty, values )

[Jan]

CELLFUN('isempty') is remarkably faster than CELLFUN(@isempty).

thank you for the answer but... I want my programme to stop when i have an non empty cell. I wan't to check the "values" and if the "values"is empty then i 'll continue my programme. Can you help me??

[Robert Cumming]

presumably you have a for loop then so that you can stop/break? i.e.

for ii=1:length(values)

if isempty ( values{ii} )

break

end

end

[Oleg Komarov]

idx = cellfun('isempty',values);

find(~idx,1,'first')

Finds the location of the first non-empty.
