Removing <missing> from cell arrays

Hello everyone!

I hope you are doing well.

I am currently trying to remove missing entries from the cell array 'InfoStatus_dias', which you can find attached here. My original attempt to do so is as follows:

    for k = 1:size(Datas_tratado,1)
        for j = 1:14
            rmmissing(InfoStatus_dias{k,1}{j,1});
        end
    end

Only to return error "Conversion of element 1 from <missing> to character vector is not supported."

Then I tried doing like so:

    for k = 1:size(Datas_tratado,1)
            rmmissing(InfoStatus_dias{k,1}{:,1});
    end
   

But it returned the same error :(

I am struggling to find where my thinking is wrong while using this loop, and... well, could you shine a light on this matter?

Thanks in advance!

Arthur.

Note that, as with most matlab functions, calling rmmissing without assigning its output to anything is a big waste of time. You're just throwing away whatever the function does.

The easiest way to do what I assume you want:

newInfoStatus = cellfun(@rmmissing, InfoStatus_dias, 'UniformOutput', false);

The loop equivalent of the above line, if you don't like cellfun:

newInfoStatus = cell(size(InfoStatus_dias));
for k = 1:numel(InfoStatus_dias)
    newInfoStatus{k} = rmmissing(InfoStatus_dias{k});  %I recommend that you use 1D indexing in vector, {k} instead of {1,k} or {k, 1}
end

Thanks a bunch!!

That's exactly what I wanted to do. I'm going to read more about cellfun :)

Best regards,

What if the cell array 'InfoSatus_dias' is e.g. a 4x10 cell array where each individual cell is a 40x1 column vector? how would you go about removing all missing entries from each of these?
