timeSeries
('Triangle', tag, tStart, tEnd, period, '-factor', factor=1.0, '-shift', shift=0.0, '-zeroShift', zeroShift=0.0) This command is used to construct a TimeSeries object in which the load factor is some triangular function of the time in the domain.
\[\begin{split}\lambda = f(t) = \begin{cases} slope*k*period+zeroShift, & k < 0.25\\ cFactor-slope*(k-0.25)*period+zeroShift, & k < 0.75\\ -cFactor+slope*(k-0.75)*period+zeroShift, & k < 1.0\\ 0.0, & otherwise \end{cases}\end{split}\]\[ \begin{align}\begin{aligned}slope = \frac{cFactor}{period/4}\\k = \frac{t+\phi-tStart}{period}-floor(\frac{t+\phi-tStart}{period})\\\phi = shift - \frac{zeroShift}{slope}\end{aligned}\end{align} \]tag
