fann_create_train_from_callback - Creates the training data struct from a user supplied function

SYNOPSIS
       resource fann_create_train_from_callback (int  $num_data, int  $num_input, int  $num_output, collable  $user_function)

DESCRIPTION
	Creates  the  training	data  struct  from a user supplied function. As the training data are numerable (data 1, data 2...), the user must
       write a function that receives the number of the training data set (input, output) and returns the set.

PARAMETERS
	      o $num_data
		- The number of training data

	      o $num_input
		- The number of inputs per training data

	      o $num_output
		- The number of ouputs per training data

	      o $user_function
		- The user supplied function with following parameters:

		     o num - The number of the training data set

		     o num_input - The number of inputs per training data

		     o num - The number of ouputs per training dataThe number of inputs per training data

	       The function should return an associative array with keys input and output and two array values of input and output.

RETURN VALUES
	Returns a train data resource on success, or FALSE on error.

EXAMPLES
       Example #1

	      fann_create_train_from_callback example

	      <?php
	      function create_train_callback($num_data, $num_input, $num_output) {
		  return array(
		      "input" => array_fill(0, $num_input, 1),
		      "output" => array_fill(0, $num_output, 1),
		  );
	      }

	      $num_data = 3;
	      $num_input = 2;
	      $num_output = 1;
	      $train_data = fann_create_train_from_callback($num_data, $num_input, $num_output, "create_train_callback");
	      if ($train_data) {
		  // Do something with $train_data
	      }
	      ?>
