# tf\_mandelbrot\*

Computes the [Mandelbrot set](https://en.wikipedia.org/wiki/Mandelbrot_set) over the complex domain \[`x_min`, `x_max`), \[`y_min`, `y_max`), discretizing the xy-space into an output of dimensions `x_pixels` X `y_pixels`. The output for each cell is the number of iterations needed to escape to infinity, up to and including the specified `max_iterations`.
