I am looking for a way to find same eigenvectors for 2 given matrices, this way I would make a joint diagonalisation. For this, I found out and tried to use qndiag (from https://github.com/pierreablin/qndiag.git ) from the following function :

The github is here : qndiag libray

I am using this Python script to compute these 2 diagonalisation as closed as possible :

The function qndiag is defined like this (not entirely source) :

I have requested that we have libsnd file installed on the hpc cluster. The admin said that I can test this via the following link:

https://raw.githubusercontent.com/erikd/libsndfile/master/examples/sndfile-to-text.c

I'm working with NetCDF and FITS files and I have Tika working for extracting the header text in NetCDF files but I can only get basic file metadata for FITS files. Does header text extraction not work on FITS files?

Followed this for FITS: https://wiki.apache.org/tika/TikaGDAL And am only seeing the basic file metadata not the actual text from the header.

This is what I'm using for NetCDF files (also used tika --gui to see the header text): curl -X -PUT --data-binary @age4_timeseries.nc http://localhost:9998/tika --header "Content-type: text/-t" curl -T age4_timeseries.nc http://localhost:9998/tika --header "Accept: text/plain"

I've looked through the Tika Jira and found a reference from 2012: https://issues.apache.org/jira/browse/TIKA-874

But this does not appear to have been added to Tika.

I received this from Tika:

I can't get the value of this XML node.

I need to get the value and give the user the possibility to change it.

I have already tried this solution, but it doesn't work:

I'm having some problems getting a node of XML document in C#

I need to make a program that enables the user to edit the of each .

I have already tried to get a node with GetElementById but it always return null and I can't understand why.

This is my xml document:

I'm fairly new to Python and I'm writing a script which should take two fairly big textfiles(~10MB) and create a new file for each, with some rules specified below in mind.

File A has tabulator-separated values on each line, file B contains ID on one line and data on the next line. IDs from file B are also present in file A, but not all IDs from file A are in file B and vice versa.

Neither file has IDs in an alphanumerical order and both files have different order. I don't need to sort them alphanumerically, I just need the output files to be in the same order and to contain only the items with common ID.

Here's how file A looks:

Here's how file B looks:

As you can see, the items from file A, column B provide the identifiers which may or may not be present in file A.

Here's a simple script I wrote. For every line from file A, it goes through the whole file B until it either finds a matching ID or reaches the end.

The script is working fine, but since it contains a nested loop, it's probably around O(n^2) (it's actually O(m*n)for m being size of file A and n being size of file B, but they are usually similar in size), which might become a problem once I'll use it on real data (hundreds of MB or units of GB).

I'm trying to parse some expression. I started from impressive answers of llonesmiz and Sehe

I wanted to add some:

(1) defined parameters. These prams are given as map by another class. They may have no argument (integer) one or two :

• imf ---> $imf
• imf(1) ---> $imf(1)
• imf(1,2) ---> $imf(1,2)

I'm traying to fist get the parameter name "imf" an then its arguments if they exist (1), (2,2) ...

(2) defined function given as a map by another class. They may have one, two or three argument :

• cos(1) ---> cos(1)
• cross(imf(1),1) ---> cross($imf(1),1)
• fun3(1,2,1) ---> fun3(1,2,1)
