XEXTRACTWIN

Purpose:

Extracts a portion of a series from multiple Windows using X values.

Syntax:

XEXTRACTWIN(W1, W2, ..., WN, xstart, xend, offset)

WN	-	Optional. Zero or more Windows. If not specified, all windows are processed.
xstart	-	A real, the starting X value.
xend	-	A real, the ending X value.
offset	-	Optional. A real, the X offset of the resulting series. Defaults to xstart, the starting X value.

Returns:

Nothing, the result of each extraction is placed into the target windows.

Example:

W1: integ(gnorm(1000, 1/1000))

W2: integ(gnorm(1000, 1/1000))

W3: integ(gnorm(1000, 1/1000))

W4: integ(gnorm(1000, 1/1000))

xextractwin(0.1, 0.4)

W1 through W4 originally contain 1000 point random series. XEXTRACTWIN extracts 301 points from each window starting at the X value 0.1 and ending at the X value 0.4.

Example:

W1: integ(gnorm(1000, 1/1000))

W2: integ(gnorm(1000, 1/1000))

W3: integ(gnorm(1000, 1/1000))

W4: integ(gnorm(1000, 1/1000))

xextractwin(W1, W2, 0.1, 0.4)

Same as above except only W1 and W2 are processed.

Example:

W1: integ(gnorm(1000, 1/1000))

W2: integ(gnorm(1000, 1/1000))

W3: integ(gnorm(1000, 1/1000))

W4: integ(gnorm(1000, 1/1000))

xextractwin(W2..W4, 0.1, 0.4, 0.0)

W1 through W4 originally contain 1000 point random series. XEXTRACTWIN extracts 301 points from W2, W3 and W4 starting at the X value 0.1 and ending at the X value 0.4. The XOFFSET for each window is set to 0.0.

Remarks:

If xstart is negative, zeros are prepended to the result. If the number of points to extract is greater than the series or table length, the result is padded with zeros.
