mandelbrot: Mandelbrot convergence counts

Description

Mandelbrot convergence counts

Usage

mandelbrot(...)

Arguments

Z

A complex matrix for which convergence counts should be calculated.

xmid, ymid, side, resolution

Alternative specification of the complex plane Z, where mean(Re(Z)) == xmid, mean(Im(Z)) == ymid, diff(range(Re(Z))) == side, diff(range(Im(Z))) == side, and dim(Z) == c(resolution, resolution).

maxIter

Maximum number of iterations per bin.

tau

A threshold; the radius when calling divergence (Mod(z) > tau).

Value

Returns an integer matrix (of class Mandelbrot) with non-negative counts.

Examples

# NOT RUN {
counts <- mandelbrot(xmid = -0.75, ymid = 0, side = 3)
str(counts)
# }
# NOT RUN {
plot(counts)
# }
# NOT RUN {
