hello

i need to find an value in a partly empty cell array with different data types (incl. serial- object) and return the index of the position of the value. let's assue we have
s1=serial('COM1');
s2=serial('COM2');
cellArray = {'aa' [] [] [] ; 'bb' [9600] [2] s2 };

so now i want to check, if there is a value ==9600 in column 2
i tried

isEqTo = arrayfun(@(x)((x{1}==9600)),cellArray,'uniformoutput',false)
>> isEqTo =
[1x2 logical] [] [] []
[1x2 logical] [1] [0] [0]

find([isEqTo{:,2}])
>> ans =
1

so the problem here seems to be that []==x (x is any number) returns [] and not 0
do you have an improvement or a better solution to solve this problem?
thx a lot

If you know in advance the number of the column and that column is numeric:

% Find TF index
tf = cellfun(@(x) isequal(x,9600), cellArray(:,2));
