For ngc6543a (.jpg and .txt)

Found this:
https://solarviews.com/cap/ds/ngc6543a.htm

The .gif file shows the footer information, which has been the difficult part.

Maybe the cross reference STScI-PRC95-01 will help?

Created sunspot.dat file based on the noaa site


load sunspot.dat
year = sunspot (:, 1);
avSpots = sunspot (:, 2);


Works as expected, however
findpeaks (avSpots, year)

Fails with this error:

error: findpeaks: non-string for Parameter name or Switch
error: called from
    error at line 573 column 7
    parse at line 474 column 11
    findpeaks at line 143 column 5


A plot was expected.
Was the file created wrong?

For sunspot.dat

I see the two things:
1) R data goes from 1700-1988
https://rdrr.io/r/datasets/sunspot.year.html

2) Activity sheet from 1700-2015
https://www.esrl.noaa.gov/gmd/outreach/info_activities/pdfs/MAA_sunspots_and_climate_change.pdf

From https://www.esrl.noaa.gov/gmd/about/disclaimer.html
It appears the information is in the public domain


ML states
average number of sunspots observed every year from 1700 to 1987

Is this just a two column file?
[year, avg_sunspots]

Or is there more information?

I added the west0479 data file in this changeset:

http://hg.savannah.gnu.org/hgweb/octave/rev/c2c528319260

I agree that we should probably create a feature request on the bug tracker instead of having a discussion here with no patch(es).

This is still not fixed, so reopening. Maybe move to bugs, feature request, instead of patch if the lack of an actual patch is an issue?

Reviewing for Octave 6 release.  I see no patches attached.  Maybe this is a discussion more suited for the maintainers-mailing list.

Closing as there is nothing to do here.

Hi,

i have a suggestion:

There is an interesting site where you can find geomaps and gravity maps for Earth, Moon and Mars, based on satelite data.
I got some of it working in Octave,some examples is extremely slowly ...

Here the link:

http://www.asu.cas.cz/~bezdek/vyzkum/rotating_3d_globe/index.php#8a

May Be interesting for Octave example data file and for various great demos.

Best regards

  • accidents.mat


This file has the following variables:


  Name              Size            Bytes  Class     Attributes

  datasources       3x1              2724  cell
  hwycols           1x1                 8  double

  ushwydata         1x17              136  double
  uslabel           1x1               138  cell


And the datasources states where the data comes from:

ans =

(Table 2-1:  Highway Traffic Fatalities and Fatality Rates: 2004)'

>> datasources{2}

ans =

    'SOURCES: U.S. Department of Transportation, National Highway Traffic Safety Administration, Traffic Safety Facts 2004: Alcohol, Washington, DC: 2005, available at http://www-nrd.nhtsa.dot.gov/departments/nrd-30/ncsa/availinf.html as of Nov. 4, 2005; U.S. Department of Transportation, National Highway Traffic Safety Administration, Fatality Analysis Reporting System (FARS) Web-based Encyclopedia, available at http://www-fars.nthsa.dot.gov as of Nov. 4, 2005.'

>> datasources{3}

    'SOURCES: Population data is from the U.S. Census of Population for 2000. State geographic centroids are not from the Census Bureau.

It would be nice to have our own data files for demos and documentation purposes since they are often more complicated than they have to by first having to generate them.  If they could be the same as matlab then even nicer since it makes it easier to compare results.  Some may be on public domain or we could ask the original authors.

The following is a list of data files in Matlab 2017b (I have already removed penny.mat which is already part of Octave):


accidents.mat
