Computes a non-overlapping block minimum of a series.
BLOCKMIN(series, N)
|
series |
- |
A series or table. |

N |
- |
An integer, the points per block to calculate the minimum as the series is processed. |
A series or table, the N-point block minimum.
W1: 1..12
W2: blockmin(W1, 2)
W2 == {1, 3, 5, 7, 9, 11}
W1: 1..12
W2: blockmin(W1, 3)
W2 == {1, 4, 7, 10}
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.
