Find location (column) of a [1] in a cell array

If I have a 1x3 cell array that looks something like this [] [] [1], or this [1][][], how would I get my code to print the index at which the 1 is? so for the first example, it's in column 3 and I would like to output a 3, and for the second example the 1 is in column 1/position 1 so I would like to output a 1. (Note: this will always be for a 1xN cell array with only one row)

find(~cellfun(@isempty, YourCell))

Those kinds of arrays are common when you are using strfind() or regexp().

It is common in such cases that using a logical vector does as well or better than finding the index, especially if there might be multiple matches:

mask = ~cellfun(@isempty, YourCell);
selected = YourOriginal(mask);

and not infrequently

mask = cellfun(@isempty, YourCell);
YourOriginal(mask) = [];

leaving only the matching entries.
