matlab - How can I remove the row of an mx3 matrix from an nx3 matrix (n>m)? -


In the matlab, if there is one mile by 3 matrix which are present in all the large 3 by the matrix, how can I create Am 3 by a matrix (nm) in which there are no rows of the first (m3) matrix?

For example if the first matrix [1 4 6] and the second matrix [1 2 3; 1 4 6; 8 7 4], how can I come up with the matrix: [1 2 3; 8 7 4]?

This is a job for the 'rows' option: 

  a = [1 4 6]; B = [1 2 3; 1 4 6; 8 7 4]; Eq_rows = ismember (b, a, 'rows'); Results = B (~ eq_rows, :)

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.

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...
