# sysid - System Identification in R

The package provides functions for constructing mathematical models of dynamic systems from measured input-output data. It lets you create and use models of dynamic systems not easily modeled from first principles or specifications. You can use time-domain and frequency-domain input-output data to identify discrete-time input-output models, transfer functions and state space models.

## Installation

You can install `sysid`

from github using the `devtools`

package.

```
require(devtools)
install_github("surajy123/R-sysid/")
```

Note: Windows users need to install the `Rtools`

executable from https://cran.r-project.org/bin/windows/Rtools/
