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: glminit.m
    path of file: ./repos/pcm/matlab/lib/netlab3_3
    
    the code of the file until where you have to start completion: function net = glminit(net, prior)
%GLMINIT Initialise the weights in a generalized linear model.
%
%	Description
%
%	NET = GLMINIT(NET, PRIOR) takes a generalized linear model NET and
%	sets the weights and biases by sampling from a Gaussian distribution.
%	If PRIOR is a scalar, then all of the parameters (weights and biases)

%	Description
%
%	NET = GLMINIT(NET, PRIOR) takes a generalized linear model NET and
%	sets the weights and biases by sampling from a Gaussian distribution.
%	If PRIOR is a scalar, then all of the parameters (weights and biases)
%	are sampled from a single isotropic Gaussian with inverse variance
%	equal to PRIOR. If PRIOR is a data structure similar to that in
%	MLPPRIOR but for a single layer of weights, then the parameters are
%	sampled from multiple Gaussians according to their groupings (defined
%	by the INDEX field) with corresponding variances (defined by the
%	ALPHA field).
