Consider 2-D geometry and assume that the points are given in form of rows of a matrix. Find the area of polygon enclosed by the points.
A = [1 2;4 5; 6 7], represents points (1,2),(4,5) and (6,7)
Do you mean "Coordinates in matrix are arranged in counter-clockwise direction"?
Yes. They are assumed to be in counter clockwise to match up with the test suites. Thanks. I have updated the definition.
Additional test cases have been added.
Sum of diagonal of a square matrix
Are all the three given point in the same line?
subtract central cross
Find elements of set A those are not in set B
