What's the MATLAB function for baseline correction of IR spectra? I have gone through the Signal Processing Toolbox documentation, but I cannot find the specific function. Below is an image of what I would like to accomplish.

It is not possible to provide specific code without your data.
See for example: Raman spectra background removal and Shifting Baselines of Raman Spectra for examples.

data = your data
order = 2 %order must be greater than 0
out = detrend(data,order)
