PARTPROD

Purpose:

Calculates the partial product of a series.

PARTPROD(series)

series

A series or table.

A series or table.

partprod({2, 4, 7})

returns the series: {2, 14, 119}.

The partial product, y, of a series, x, is computed as follows:

y[1] = x[1];

loop (j = 2..length(x))
{
y[j] = (x[j] + 1) * (y[j-1] + 1) - 1;
}

See CUMPROD to calculate the cumulative product.
