maxstar(x) is the natural log of a sum of exponentials overcoming the numerical failure of log(sum(exp(x))) for extreme values of an argument vector x.
maxstar(x,[],dim) has the N-D array features of the MATLAB max function.
maxstar(x,w,dim) is the natural log of a weighted sum of exponentials.
The max* function is described in Lin & Costello, Error Control Coding, 2nd Edition, equation 12.127.
