Baseline Correction of IR Spectra

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.

Hi Star,

Thanks for the response.

Apologies for not being clear.

I am looking for a MATLAB built-in function. So I can also read the documentation and the math behind the methods. Also, I was optimistic that the built-in function would have more options (or input parameters) that offer added flexibility and fine-tuning capabilities.

I have previously tried the methods at the links that you have provided, but they seem to have some limitations when it comes to processing multiple IR spectra.

Cheers.

‘I am looking for a MATLAB built-in function.’

There isn’t one.

Each spectrum has to be analysed and processed individually.
