Hello,

I have encountered this problem in one of my codes (reproduced here with simple data) :

vect =  [1 2 4 3]; % creating a vector
mat = [vect;vect]; % juste a simple matrix
% initialising a table
varnames = {'SomeTableCellData'};
vartypes = {'cell'};
Table = table('Size',[0 length(varnames)],'VariableTypes',vartypes,'VariableNames',varnames);
% this works
Table(1,'SomeTableCellData') = {mat};
% this doesn't work
Table(2,'SomeTableCellData') = {vect};  

But both {mat} and {vect} are cell arrays containing double, so I'm a bit lost as why this happens.

Thanks for your help.

Does work with a column vector:

vect =  [1 2 4 3]'; % creating a vector and transpose it
mat = [vect, vect]; % juste a simple matrix
% initialising a table
varnames = {'SomeTableCellData'};
vartypes = {'cell'};
Table = table('Size',[0 length(varnames)],'VariableTypes',vartypes,'VariableNames',varnames);
% this works
Table(1,'SomeTableCellData') = {mat};
% this doesn't work
Table(2,'SomeTableCellData') = {vect};

Interesting... Didn't thought of that, thanks.

Still is a strange error though

Hi,

I have brought this issue (with the row vector while assignment to a table) to the notice of our developers. They will investigate the matter further.
