matlab - How to remove specific elements of a matrix? -

-

I'm having a bad day at work. I have a very simple question.

I have 2x100 metrics, such as 

  [1 2 3 4 5 6 -2 -3 .... 2 4 5 3 2 -4 3 3 ..]   
 To examine the first line of the matrix and delete all the numbers above 2 and remove the associated entry line 2. So for example, if there is only 1 element in comparison to the upper case then our matrix will become 2x99 matrix.   
 
 
 You should use logical sequencing:  
  idxToKeep = yourMat (1, :) & lt; = 2; NewMat = yourMat (:, idxToKeep);   
 Or if you do not want to create a new matrix:  
  yourMat = yourMat (:, idxToKeep);   
 or all in one-liner:  
  yourMat = yourMat (:, your Mate (1, :) & lt; = 2);

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

python - 'NoneType' object is not callable using 'find_all' in BeautifulSoup -

Here's my code using find_all, but this is my code. Works great with: (): To get beautiful suits R = requests from beautiful soup imports to import. (URL_DEFINED) Print Rustusodod Soup = Beautiful Soup (Rtext) Print soup.fund_all ('ul') What I found: Tracebacks (Most recent call end): File "scraper.py", line 1 9, & lt; Module & gt; Print soup.find_all ('ul') TypeError: The 'NoneType' object is not worth the corner It seems that you are using Sundersup version 3, in which a slightly different naming convention is used, such as: .findAll , while SunderSupo 4 standardized naming, like more PEP8, Such as: .find_all (but retains the old naming for previous compatibility) Note that soup ('ul') is equal to both search for all . To download and install, install pipes PrettySpeed ​​4 . Then to change your import: import from bs4 BeautifulSoup Then you are good go.
