iFit/maxwell

 y = Maxwell(p, x, [y]) : Maxwellian

   iFunc/Maxwell Maxwellian fitting function
     Sum of 3 Maxwellian distributions

 Reference: http://en.wikipedia.org/wiki/Maxwell%E2%80%93Boltzmann_distribution

 input:  p: Maxwellian model parameters (double)
            p = [ 'T1','I1','T2','I2','T3','I3' ]
          or 'guess'
         x: axis (double)
         y: when values are given and p='guess', a guess of the parameters is performed (double)
 output: y: model value
 ex:     y=Maxwell([1 0 1 1], -10:10); or plot(Maxwell);
