Computes the empirical cumulative distribution function (ECDF), accounting for
the presence of ties. Useful for bootstrap statistics, which often contain ties.

'[x, F] = bootcdf (y)' computes the empirical cumulative distribution
function (ECDF) of the vector y of length N. This funtction accounts for
the presence of ties and so is suitable for computing the ECDF of
bootstrap statistics.
'[x, F] = bootcdf (y, trim)' removes redundant rows of the ECDF when trim
is true. When trim is false, x and F are are the same length as y. The
default is true.
'[x, F] = bootcdf (y, trim, m)' specifies the denominator in the
calculation of F as (N + m). Accepted values of m are 0 or 1, with the
default being 0. When m is 1, quantiles formed from x and F are akin to
qtype 6 in the R quantile function.
'[x, F] = bootcdf (y, trim, m, tol)' applies a tolerance for the absolute
difference in y values that constitutes a tie. The default tolerance
is 1e-12 for double precision, or 1e-6 for single precision.
'[x, F, P] = bootcdf (...)' also returns the distribution of P values.
