Open field tropical horticulture production is highly affected by the uncontrollable environment. Consequently, farmer manages their farming activity so as to adapt the environment, such as an appropriate planting schedule, plant maintenance, and daily irrigation. Nowadays, climate change intensifies unpredictable weather and unstable climate distribution. The precision farming approach was introduced by the utilization of … Read more

[latexpage] At first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^*$: \[ f_k = f(x_k),\: x_k = x^*+kh,\: k=-\frac{N-1}{2},\dots,\frac{N-1}{2} \] where $h$ is some step. Then we interpolate points $\{(x_k,f_k)\}$ by polynomial \begin{equation} \label{eq:poly} P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j} \end{equation} Its coefficients $\{a_j\}$ are found as a solution of system of linear equations: \begin{equation} \label{eq:sys} \left\{ … Read more
