MATLAB solver, calling on pre-defined variables within the equations -


So I'm wondering how to input the pre-defined variables in the equations themselves.

Here's the code. 

  function [A, B, C] = A_B_C_problem_generalized (lambda_1, lambda_2, mu_1, mu_2, gamma_1, gamma_2) Clear clc syms a1 a2 a4b1b2b4 c1 c2c4 [A1, A2, A4, B1, B2, B4, C1, C2, C4] = ... solution ('a1 + a4 = lambda_1 + lambda_2' ... 'a1 * a4 - a2 ^ 2 = lambda_1 * lambda_2 ', ... ..' B1 + B4 = mu_1 + mu_2 ', ...' B1 * b4 - b2 ^ 2 = mu_1 * mu_2 ', ...' c1 + c4 = 'Gamma_1 + gamma_2', ... 'c1 * c4 - c2 ^ 2 = gam_1 * gam_2', ... 'c1 = a1 + b1', ... 'c2 = a2 + b2', ... ' C4 = a4 + b4 '); ...   
 How can I go about doing this? The number of lambda's, mu k, and gamma is expected to be added to you.   
 After 
 
 Ah, the right approach was not to use the wire instead, instead it was converted to a problem of finding roots. , Which the solver himself does, if you take everything on one side of the equation ...    B2, b4, c1, c2, c4] = ... solution (a1 + a4 - (lambda_1 + lambda_2), ... a1 * a4 - a2 ^ 2 - (lambda_1 * lambda_2), ... b1 + b 4 - (mu_1 + mu_2), ... b1 * b4 - b2 ^ 2 - (mu_1 * mu_2), ... c1 + c4 - (gamma_1 + gamma_2), ... c1 * c4 - c2 ^ 2 - (Gamma_1 * gamma_2), ... C1 - A1 - B1, ... c2 - A2 - b2, c 4 ... - A4 - B4)   
 is the way to go

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.

I use Eners to be hibernate to audit my institutions.

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...
