Financial time series subtraction
newfts = tsobj_1 - tsobj_2 newfts = tsobj - array newfts = array - tsobj
A pair of financial time series objects .
A scalar value or array with the number of rows equal
to the number of dates in
minus is an element-by-element subtraction
of the components.
newfts = tsobj_1 - tsobj_2 subtracts financial
time series objects. If an object is to be subtracted from another
object, both objects must have the same dates and data series names,
although the order need not be the same. The order of the data series,
when one financial time series object is subtracted from another,
follows the order of the first object.
newfts = tsobj - array subtracts an array
element by element from a financial time series object.
newfts = array - tsobj subtracts a financial
time series object element by element from an array.
