Sierpinski Fractal Triangle

Bearable algorithm which provides a Sierpinski Fractal Triangle image.

This function provides a bearable algorithm for generating a fractal image, in particular, the Sierpinski Triangle. The function opens a new figure and plots the result for a given number of iterations, which must be greater or equal than 0. It should be taken into consideration that the more iterations, the more computation time.
Example of use:
sierpinski_triangle(6);
