## Baseline Correction using asymmetric least squares

### Description

This function estimates a baseline using asymmetric least squares and subtracts it from the data.

### Usage

    baseline.corr(y, ...)

### Arguments

`y` | signal(s) to correct. This can be a vector (containing one signal) or a matrix of signals(one signal per row)
`...` | other arguments to the `asysm` function.

### Value

`ycorr` | baseline corrected signal(s): a vector or a matrix of the same dimension as the input signal(s)
