Computes a Multivariate Analysis of Variance for equal or unequal sample sizes. Testing of the mean differences in several variables among several samples (groups).

This MATLAB macro consider the matrices of sum-of-squares between (H) and within (E) to compute the Wilks'lambda (L) and according to the number of data it chooses to approximate to the Chi-square distribution (large sample) or through several multiple F-aproximations such as Rao, Pillai, Lawley-Hotelling and Roy tests (small sample).

It needs to input the X-data matrix [size of matrix must be n-by-(1+p); sample=column 1, variables=column 2:p]and alpha-significance (default = 0.05). The output is a complete multivariate analysis of variance table.

Due to a lack of appreciation of the Roy's maximum root multivariate test, it was adequately corrected.
