poly_simplify

poly_simplify uses the Douglas-Peucker algorithm to simplify a 2D line.

rmXYOut = poly_simplify(nSteps, rsTol, x, y)

Return Value

rmXYOut is a matrix with two columns. The first column contains the x and the second column the y coordinates. In case of an error the function returns a scalar value -1.

Parameters

nSteps

Number of iterations or -1 if the parameter rsTol should be used.

rsTol

sets the tolerance. If rsTol is 0 and nSteps is -1, the calculated curve is identical to the original curve but all unnecessary points are removed.

x

is a vector with x coordinates.

y

is a vector with y coordinates.

Example

* poly_simplify(-1, 0, [1,2,3], [1,2,3])
    1.0000     1.0000
    3.0000     3.0000
