                Posted - 03/09/2014 : 09:58:07 AM  Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 8.5.0 SR1  Operating System: win7 Hello, Where can I find the origin built-in function list?  I want to define a function for nonlinear fitting. This function has a "sech" function inside. I need to know whether "sech" is available in Built-in function list. I looked for the Origin help, But cannot find a list for Built-in function. I know there is a drop-down list of functions when openning the set column values dialog. I am just wondering whether there is a full built-in functions list and instructions in the Origin help documents. This really sometimes frustrates me when I want to define a new function.
  Thanks for your help.
