get the position of each number

Hi, I've got a variable that gives me all the messages that have the value I asked for.

What I want is to get a variable that gives me the position where I can find the number 215382000 the final output would be:

first cell = 5

second cell = 6

third cell = 10

fourth cell = 11

like this. Here I upload the data too

Assuming you just want the non-empty cells

idx = find(~cellfun(@isempty,Msg_mmsi_selected))

I noticed you accepted Cris' answer. His answer works, but I think the approach I have here does the same thing in just one line. That would seem preferable. I'm wondering if there is something that I missed.

Both make the same, it was ust the first one I saw. Yours is better just 2 variables less

Not sure of a single function solution, but this works.

load msg_mmsi_selected
ind = ~cellfun("isempty",Msg_mmsi_selected);
V = 1:length(Msg_mmsi_selected);
c = V(ind)

c = 1×61456

5 6 10 11 13 15 21 32 44 48 54 55 66 67 73 74 77 80 87 89 92 96 100 104 112 121 128 131 132 133
