question about basecorr

[chemshd]

I find that the function of "basecorr" is very useful, since my spectrometer always has a problem with the baseline.
But I do not really understand what does the "Dim" input mean in the description.
Is it necessary that the input Spec is 1D array? or do I have to include the field information in the Spec?
If Spec is 1D, then what does the dim do there?

The Dimension specifies along which dimension basecorr() should apply the baseline correction. If your data is 1D, then this depends on whether it's a 1D column vector, or a 1D row vector. For the column vector, apply it along dimension 1, and for the row vector along dimension 2.
