How to define the location/position of a number in a specific cell array?

I have a question about a command in a code.

I have a 82x1 cell array named MY. In this array there is a number equal to "1" in the line 41. I would like to find the location/position of this number in this array (I mean I would like to have as a result the 41 line number). The other elements of this array have punctuations marks "[]" (see image uploaded

I tried to use:

location=find(table2array(MY{:}) == 1)

but it is no use ( I mean I want to have location=41).

Could you please help me?

It would help to have the actual cell array.

Try something like this —

MY = {[]; []; []; 1; []; []; []}

MY = 7×1 cell array
    {0×0 double}
    {0×0 double}
    {0×0 double}
    {[       1]}
    {0×0 double}
    {0×0 double}
    {0×0 double}

loc = find(cellfun(@(x)~isempty(x), MY))

loc = 4

Code revision (improved efficiency).

idx = find(cellfun(@(x)isequal(x,1),MY));
