Generate and total Leslie population states

Question 1 of 8

Calculator allowed

A dune-restoration model records grasses in equal-width growth stages. The same rates apply in every model period

Use the group order new sprouts, juvenile plants, and established plants. One application represents one growing season. The groups have equal widths, so a survivor advances one group in one application

This model counts all individuals. A fertility entry is the expected number of new first-group entrants per current individual in one period. A survival entry is the proportion advancing from one group to the next

\[L=\begin{bmatrix} 1.2 & 1.4 & 1 \\ 0.8 & 0 & 0 \\ 0 & 0.6 & 0 \end{bmatrix}\]
\[S_0=\begin{bmatrix} 15 \\ 40 \\ 30 \end{bmatrix}\]
\[S_{n+1}=L S_n\]

The entries of each state column are expected counts of plants
