Calculate the co-ranking matrix to assess the quality of a diminsionality reduction.

## Usage

```
coranking(
Xi,
X,
input_Xi = c("data", "dist", "rank"),
input_X = input_Xi,
use = "C"
)
```

## Arguments

- Xi
high dimensional data

- X
low dimensional data

- input_Xi
type of input of Xi (see. details)

- input_X
type of input of X (see. details)

- use
`R`

or`C`

backend

## Details

Calculate the coranking matrix, to assess the quality of a dimensionality
reduction. `Xi`

is input in high dimensions, `X`

is input in low
dimensions the type of input is given in `input_Xi`

and `input_X`

,
they can be one of `c('data', 'dist', 'rank')`

.
