Hi, I'm trying fisheriris on statistic toolbox. I make a decision tree and i want to test it with a test dataset.I try to do it with cost = test(t,'test',X,y) function.I import a dataset from sgi dataset page iris.test named dataset. but everytime i try, i get an error message.i import test number for X and label for y.Error message is "??? Undefined function or method 'isnan' for input arguments of type 'cell'.
" How should i use this function.please help me.

maybe the data vectors is cell and function needs mat
try convering it
datamat=cell2mat(datacell)

hi again, datamat=cell2mat(datacell) didnt work but after that i found cellfun function. so thank you very much giving me the thought. it helped so much.have a nice day.
