2 views (last 30 days)
I have done with classification learner for training algorithm, i have explor to model to workspace for testing the data, my input data in classification learner are import from excel (table) but for testing i want to use user input, i come out with this code. (one more thing if i import data from excel file, the testing data can classifiy but i dont want this way)
H2_percentage=15.217
CH4_percentage=53.261
C2H6_percentage= 31.522
testing=[H2_percentage CH4_percentage C2H6_percentage];
yfit = FineKNN.predictFcn('testing');
but when i run that code come out with this error....

yfit = FineKNN.predictFcn(testing);
You should use this instead.
