finding cells with positive values in a cell array with empty cells, cells of positive integers, and cells of nans

Dear Experts,

I would like to have the number and indices of cells with positive values in a cell array with cells of positive integers, empty cells and nans.

The solutions I have found in this topic were not suitable.

Please, find the array attached.

Many thanks

LG

So, what were those? No point in repeating the unwanted...

Dear dpb,

I was playing around with the following suggestions;

OutOfRange = (mycell > 0);

NrOutOfRange = sum(OutOfRange);

or

idx = find([mycell{:}] > 0);

or

idx = cellfun(@(x)~isempty(x) && x > 0, mycell);

Regards

>> idx=cellfun(@(c)any(c>0),co_burst);
>> whos idx
  Name        Size              Bytes  Class      Attributes

  idx       856x340            291040  logical              

>> sum(idx,'all')
ans =
    72
>> 

or, the locations...

>> [r,c]=ind2sub(size(idx),find(idx));
>> [r(1:5) c(1:5)]
ans =
     5     1
     8     4
    31    13
    34    15
    55    25

Dear dpb, great, many thanks, works well. The 'all' option for sum works from 2018 I,think, but I could overcome the issue.

Thanks again.
