%UT_SIGMAS - Generate Sigma Points for Unscented Transformation
%
% Syntax:
%   X = ut_sigmas(M,P,c);
%
% In:
%   M - Initial state mean (Nx1 column vector)
%   P - Initial state covariance
%   c - Parameter returned by UT_WEIGHTS
%
% Out:
%   X - Matrix where 2N+1 sigma points are as columns
%
% Description:
%   Generates sigma points and associated weights for Gaussian
%   initial distribution N(M,P). For default values of parameters
%   alpha, beta and kappa see UT_WEIGHTS.
