If you could re-run your data with this form and confirm with me that would be great!Įdit: I tried with some sample data and I can't figure out why but the form as you posted gives a better estimate for the function. I'm curious if you've found out why SciDAVis chooses this form of the Gaussian? The proper form using the FWHM should be, note the additional $ln(4)$ occurring in the square root and in the exponent: I'm actually glad you asked this question because I was convinced that I made an error when my equation looked nothing like what you had. Cell values in tables can be computed using standard and special functions (. classes and enums directly into the documentation. muParser is purely a parser for mathematical expressions and as such does not support executing complex scripts. Data for tables or matrices can be entered directly or imported from ASCII files. Setting the INLINESOURCES tag to YES will include the body of functions. muParser The constants eeE and pipiPIPi are defined, as well as the operators and functions listed below. In this way SciDAVis would have also a Gaussian fit option for statistics. I can provide a screenshot of my derivation if you're interested but this comes from substituting SciDAVis supports different interpreters for evaluating mathematical expressions and for executing scripts. There is an inconsistency between the Gauss and GaussAmp fit functions available in SciDAVis. The form of the exponent in your example is indeed not the FWHM, instead, I spent the past day doing this very derivation and I'm glad to see that someone else had the same question.
