# math: Mathematical Time Series Operations

## Description

Functions and methods dealing with mathematical 'timeSeries'
operations.
## Arguments

x

an object of class `timeSeries`

.

...

arguments to be passed.

## Value

Returns the value from a mathematical or logical operation
operating on objects of class 'timeSeries[], or the value
computed by a mathematical function.

## Details

The math functions include:

`Ops-method` |

Group 'Ops' methods for a 'timeSeries' object |

`Math-method` |

Group 'Math' methods for a 'timeSeries' object |

`Math2-method` |

Group 'Math2' methods for a 'timeSeries' object |

`Summary-method` |

Group 'Summary' methods for a 'timeSeries' object |

## Examples

## Create an Artificial timeSeries Object -
setRmetricsOptions(myFinCenter = "GMT")
charvec = timeCalendar()
set.seed(4711)
data = matrix(exp(cumsum(rnorm(12, sd = 0.1))))
TS = timeSeries(data, charvec, units = "TS")
TS
## Mathematical Operations: | +/- * ^ ... -
TS^2
TS[2:4]
OR = returns(TS)
