I know that the assumption for the Naive Bayes classifier is that the features are independent, but what if we want to check if that applies to our data? How would we do test it using Matlab?

For a 2-dimensional matrix, if the determinant is zero, then at least two rows or two columns are linearly dependent.
You can also do a principal component analysis in order to know in which direction the variation is significant.

The determinant would be 0 for non-square matrices.
You could check whether rank() was min() rows, cols, with anything less implying dependence beyond the usual.
