nansum

Sum ignoring NaNs

nansum is not recommended. Use timetable instead. For more information, see Convert Financial Time Series Objects fints to Timetables.

Syntax

y = nansum(X)
y = nansum(X,DIM)

Arguments

X	Financial time series object.
DIM	Dimension along which the operation is conducted.

Description

nansum for financial time series objects is based on the Statistics and Machine Learning Toolbox™ function nansum. See nansum.

y = nansum(X) returns the sum of a financial time series object X, treating NaNs as missing values. y is the sum of the non-NaN elements in X.

y = nansum(X,DIM) takes the sum along dimension DIM of X.

Examples

To compute nansum for the following dates:

dates = {'01-Jan-2007';'02-Jan-2007';'03-Jan-2007'};
f = fints(dates, magic(3));
f.series1(1) = nan;
f.series2(3) = nan;
f.series3(2) = nan;

nsum = nansum(f)
