TASK$-2("$BASICS$"$ of Linear Classifiers and SVM$)$

A rectangular forest block is shown in the Figure, which also shows with small circles trees$/$plants on this block of land. Coordinates of its corners can be retrieved from the title of the Figure.

$$ Exact XX and YY coordinates for each plant are provided in the MATLAB data file, which can be retrieved from EXCEL data, you can retrieve the same coordinate numbers XX and YY from the Excel file $($which has no headings, and which has XX and YY coordinates saved in the first and second columns$)$:

Download the XLS file on your current MATLAB directory and, for example, run $">>$data$=$xlsread$(\text{'}$a$2\_$linear$\_$classifier$\_$data$\_$UU$.$xlsx$\text{'})$;

XX$=$data$($:$,1)\text{'}$; YY$=$data$($:$,2)\text{'}$;$"$ from Command window or include as proper command in MATLAB script. Note: provided MATLAB sample commands load XX and YY as rows $($and not as columns$).$ Omit transposition signs to get XX and YY as columns.

Forest block has been divided by its diagonals into four triangular areas, and trees$/$plants in the area of interest were marked by black $"$x$"$ symbols.

USE LINEAR CLASSIFIERS and DETERMINE THE NUMBER OF PLANTS in the area, marked by $"$x$".$
