Say I have a matrix of type double, of dimensions m x n, and a cell array of strings, dimensions 1 x n, holding the names of the columns of the matrix.

How do I use the dataset command to create a dataset from these variables, using the cell array as the column names.

I have tried dataset(<matrix>, <cellarray>), and dataset(<matrix>, 'VarNames', <cellarray>) and dataset({<matrix>, <cellarray>}). I keep getting an error that the number of variables and column names do not match.

Any help?

Thanks

In = rand(100,2);
varnames = {'name1','name2'};
dataset({In, varnames{:}}) % dataset({<matrix>, <cellarray{:}>}).

The dataset(<matrix>, 'VarNames', <cellarray>) doesn't work because it should be:
dataset(<vector1>,<vector2>,...,<vectorN> 'VarNames', <cellarray(1:N)>)
