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'})

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()
