@Rya: Andrei asked for a small example. You have posted your complete code with images, documentation, logos, auto-save files, several fig and m-files. What do you expect? That we inspect all of this code only to answer this simple question? The screenshot of the GUI is not useful here also.
You asked for "number(output) lies in cellarray". Then please provide how the number is represented and the typical contents or the cell array. Any further information is a waste of time only.

the number is stored in variable (noPlate) and output shows in editbox
set(handles.edit1,'string',noPlate);
here is a cell array ('ANPR.mat')
now how to check whether the output no lies in cell array or not

[truefalse, index] = ismember('abc', {'xyz', 'abc', 'def', 'abc'})
This one?

Note that you had
ANPR=['AED632' 'KPT295' 'AKH343' 'AFR420']; %cellarray
That does not create a cell array. You needed
ANPR={'AED632' 'KPT295' 'AKH343' 'AFR420'}; %cellarray

The suggested
nnz(ismember('EK94P8',ANPR(:,2)))
should be
nnz(ismember(ANPR(:,2), 'EK94P8'))
When you use ismember(A, B) then for each entry in A, a logical value (true or false) will be returned indicating whether that entry in A was found in B. So if you reverse the order like I show, then for each entry in your second column of ANPR, you are comparing it to the one value 'EK94P8', returning a logical value for each. The number of matches is the same as the number of places the logical value is true, which is the same as the number of places the logical value is non-zero. The number of places that a value is non-zero can be tested with nnz()
