Let A,B be 1-dimensional arrays, M be a 2-dimensional array.
MAT GET POINT A,B
obtains the coordinates of the points of number of the size of the array.
MAT GET POINT M
Let n be a numeric expression.
MAT GET POINT A(n),B(n)
Before execution, arrays are re-sized.
MAT GET POINT M(n,2)
MAT GET POINT: A(?),B(?)
While the left button of the mouse is pressed, the obtained coordinates are substituted for the arrays.
MAT GET POINT: M(?,)
The size of the arrays are adjusted by the number of the points obtained.
If the amount of the arrays has reached the upper bound, the execution ends.
