I have a table that contain array of double in every cell. It looks like this:
Column1 Column2
____________ ________________
1×7 double 1×27 double
1×7 double 1×27 double
1×7 double 1×27 double
1×7 double 1×27 double
1×7 double 1×27 double
But I need every cell to be 7x1 or 27x1, respectively (data in column vector, not row vector). How can I transpose it?

Are your data truly in a table data object? Or possibly in a cell array (which is arguably the more common method for storing data like this)?

Ran in:
% If data are in a cell array
c = {rand(1,7),rand(1,27)}
c = 1×2 cell array
{[0.2034 0.5277 0.8087 0.4063 0.0021 0.1522 0.6562]} {[0.3394 0.3716 0.9851 0.2202 0.6112 0.0657 0.3078 0.1728 0.0608 0.9520 0.0747 0.5836 … ]}
ctrans = cellfun(@transpose,c,'UniformOutput',false)
ctrans = 1×2 cell array
{7×1 double} {27×1 double}
% If data are in a table, convert to cell array, transpose, and convert back
t = table(rand(1,7), rand(1,27), 'VariableNames', {'t1','t2'})
t = 1×2 table
t1 t2 __________ ___________ 1×7 double 1×27 double
ct = table2cell(t);
cttrans = cellfun(@transpose,ct,'UniformOutput',false);
ttrans = cell2table(cttrans)
ttrans = 1×2 table
cttrans1 cttrans2 ____________ _____________ {7×1 double} {27×1 double}
There might be a more direct way to do this operation on a table, but I didn't think of one. Also, you'll need to rename the table variables.

The data are in table format, at least according to "Value" field in workspace. I know it is less common for data like this, but it is a part of bigger code. Anyway, the second solution with conversion to cell, and then cellfun, works fine, thank you!
