Is it a 1 by 6 array?
Filme moses This is a matlab built in function called knnclassify, which is primarily used to identify the nearest neighbour of a data in matrix. The knnclassify () function uses the k-nearest neighbours classification algorithm to perform classification. The crossvalind () function is a separate one to divide a data set in to folds to perform cross-validation. Both are part of the Bioinformatics toolbox. A way to find out if the function is available in Matlab is typing which knnclassify. The output will be the route where the function resides or 'knnclassify' not found.

This MATLAB function returns a k-nearest neighbor classification model based on the input variables (also known as predictors, features, or attributes) in the table Tbl and output (response) Tbl.ResponseVarName. ClassificationKNN is a nearest-neighbor classification model in which you can alter both the distance metric and the number of nearest neighbors. Because a ClassificationKNN classifier stores training data, you can use the model to compute resubstitution predictions. Alternatively, use the model to classify new observations using the predict method.
