extfield - Data series extraction

Syntax

ftse = extfield(tsobj, fieldnames)

Arguments

`tsobj`	Financial time series object
`fieldnames`	Data series to be extracted. A cell array if a list of data series names (`fieldnames`) is supplied. A string if only one is wanted.

Description

ftse = extfield(tsobj, fieldnames) extracts from tsobj the dates and data series specified by fieldnames into a new financial time series object ftse. ftse has all the dates in tsobj but contains a smaller number of data series.

Examples

extfield is identical to referencing a field in the object. For example,

ftse = extfield(fts, 'Close')

is the same as

ftse = fts.Close

This function is the complement of the function rmfield.
