Posted - 06/18/2007 : 12:49:38 PM Hi, I wanna fit a curve with userdefined expression. I know how to use the NLCT function. The problem is I can not input my expression in Origin. There is an erf function in the expression, but when i compile the expression, it says error with the erf function.
Is erf function involved in Origin, or how can i do it? (I tried to input the eqution of erf function, but it tells me there is no int function...)
Many many thanks :-)
