Error using 'mvregress' function
显示 更早的评论
I'm trying to use 'mvregress' function to fit Y matrix (3400x9) of dependent variables, using X matrix of observations (3400(observations) x 900 (variables)).
Y matrix has a lot of 0s, but otherwise all positive numbers between 0.7 and 1300.
When I type beta = mvregress(X,Y)
I get the error message: ??? Undefined function or method 'isnan' for input arguments of type 'cell'.
Error in ==> mvregress at 238 if isempty(EstMethod) && ~any(isnan(Data(:)))
What am I doing wrong or how can I overcome this ?
Thanks a lot ! Dusan

From the error it appears that the X or Y or both may be cell instead of matrices. You can verify that by using class as Walter mentioned or running the >>whos command. Convert them to matrices by using cell2mat http://www.mathworks.com/help/matlab/ref/cell2mat.html
