I keep encountering an error when trying to create an iddata object, and I can't understand why

Hello,
I am trying to convert a vector to an iddata object. I have a vector (y) of dimension [7800 X 1],and there is nothing particularly unique about it.
If try to convert to an iddata object as follows:
y = iddata(y);
I get the following error:
Error using iddata (line 193)
The value of the "OutputData" property must be a double matrix or a cell array of such matrices.
I can't for the life of me figure out what is wrong with my timeseries. I'm able to convert vectors of random numbers to iddata object. Does anyone have a clue why I'm getting this error.
All my thanks.

Thanks man. In my problem they were two important points;
1) Convert type single to double ie. double(y).
2) Take transpose.

Um, I figured it out. My vector was single precision.

Thanks for the answers. I got the same issue. After converting the data to "double" data type, it works good.
