I have a Dataset as follows:

Dataset =

4×2 cell array

{1×3 double} {0×0 double}

{1×3 double} {1×67 double}

{1×3 double} {0×0 double}

I want to merge Dataset{2,1} and Dataset{2,2} and resulting outcome will be

Dataset =

4×1 cell array

{1×3 double}

{1×70 double}

{1×3 double}

How can I do that?

Thanks in advance!

Couldn't you just do it in a loop?

DataMerge = cell(4,1);
for j = 1:4
    DataMerge{j} = [Data{j,1},Data{j,2}]
end

Actually, if you know that only the second row of Data will ever have a non-empty matrix in column 2, you can just do

DataMerge = Data(:,1);
DataMerge{2} = [Data{2,1},Data{2,2}];
