# BLOCKMIN

## Purpose:

Computes a non-overlapping block minimum of a series.

## Syntax:

BLOCKMIN(series, N)

series |
- |
A series or table. |

N |
- |
An integer, the points per block to calculate
the minimum as the series is processed. |

## Returns:

A series or table, the N-point block minimum.

## Example:

W1: 1..12

W2: blockmin(W1, 2)

W2 == {1, 3, 5, 7, 9, 11}

## Example:

W1: 1..12

W2: blockmin(W1, 3)

W2 == {1, 4, 7, 10}

## Remarks:

BLOCKMIN computes the N-point non-overlapping
block minimum of a series by decimating
the standard N-point moving minimum.

If the block size is not an integral fraction
of the series length, the end points
are not processed.
