I am trying to classify training and testing data using "classify" command but unluckily i'm getting an error.
Error using classify
The pooled covariance matrix of TRAINING must be positive definite.
I have following training and testing data:
Training Features with 13320x7 dimensions, where I have 13320 observations and 7 features.
Training Labels with 13320x1 dimensions,
and
Testing Features 106807x7 dimensions, where I have 106807 observations and 7 features
Testing Labels with 106807x1 dimensions.
I have tried PCA, reduced features from 7 to 5, 3 and 1 but it didnt worked.
