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}
{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}
{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}];
