You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: gmmLINactiv.m
    path of file: ./repos/pcm/matlab/lib/netlab3_3
    
    the code of the file until where you have to start completion: function a = gmmLINactiv(mix, x,w)
%GMMACTIV Computes the activations of a Gaussian mixture model.
%
%	Description
%	This function computes the activations A (i.e. the  probability
%	P(X|J) of the data conditioned on each component density)  for a
%	Gaussian mixture model.  For the PPCA model, each activation is the
%	conditional probability of X given that it is generated by the
%	component subspace. The data structure MIX defines the mixture model,
%	while the matrix X contains the data vectors.  Each row of X
%	represents a single vector.
