I am trying to use an array originally, which is data read from a file, and then Calculates the meaning and standard deviation from the data by using that array.

I can not get the right number right now. Stable public double [] [] calcStats (string [] [] x) throws IOException {double [] [] array = new double [7] [2]; Double total = 0, std_dev = 0, zodiac = 0; Int row2 = 0; {Array [line2] [0] = (total) for (line line = 1; row; lt; x.length; line ++); Array [row 2] [1] = amount of mathematics (amount); Zodiac = 0; Total = 0; If (line & gt; = 2) {row2 ++; } (Int col = 1; col & lt; x [row] height; cola ++) {total + = integer ParseInt (x [row] [col]); If (colley == 4) {total = (total / 4); }} For (int col = 1; col & lt; x [row] .length; col ++) {std_dev = (integer. ParseInt (x [row] [col]) - (total); Std_dev = Math.pow (std_dev, 2); Zodiac = + std_dev; Std_dev = 0; If (colley == 4) {zodiac = (zodiac / 27); }}} Array [row 2] [0] = (total); Return array; }

Array starts with 0 in Java. You are starting your end on 1. This means that you are not remembering the first element of each array.

According to Marco Topolony's suggestion, let me tell you that I have zodiac = + std_dev; zodiac + = std_dev in its original code Now that I think about it, it was an invalid edit because the original code was an additional problem (except for the limit of the loop) I rolled back the edit to Marco's version.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
