Error using gmdistribution for GMM
显示 更早的评论
Hi, I am trying to create a GMM model for my dataset X which is of size 200x39. At the line gm = gmdistribution(mu, sigma, pcomponents), I am getting the following error
"Error using checkdata (line 18) X must be a matrix with 39 columns.
Error in gmdistribution/pdf (line 16) checkdata(X,obj);"
Size of mu -> 32x39, sigma -> 39x39x32, pcomponents -> 1x32
My X is infact having 39 columns. So I am not able to understand what exactly is causing the error. Any hint would be of great help. Thanks in advance.

Check the sizes of mu, sigma,pcomponents you are entering into the function?
For your data of 200x39, sigma should be 39x39 or 1X39 and pcomponents should 1x200.
