## Calculate an orthonormal basis

### Description

ONB = orth(mat) is an orthonormal basis for the range of matrix mat. That is, ONB' * ONB = I, the columns of ONB span the same space as the columns of mat, and the number of columns of ONB is the rank of mat.

### Usage

    orth(mat, skipInac = FALSE)

### Arguments

`mat` | matrix to calculate orthonormal base
`skipInac` | do not include components with precision below .Machine$double.eps if TRUE

### Value

orthonormal basis for the range of matrix
