Hi Wile,
Thanks, yes i can read it from ascii file but the parameters are not fixed to the values shown
in ascii file…because when i use “func” to fit a histogram, i see [0], [1] and [2] are completely different than the values in ascii file. How can i fix those parameters to the values shown in ascii file…
For example i want [0] to be fixed to 0.3, and [1] to be fixed to 0.4, and [2] to be fixed to 0.13.
