php2mat

php2mat exports data (arrays) from PHP to MAT format i.e. MATLAB® binary file based on Release 14SP3 of:

http://www.mathworks.com/access/helpdesk/help/pdf_doc/matlab/matfile_format.pdf

some basic caracteristics of MATLAB must be considered

• the length of variable names is limited see namelengthmax
• matrices are saved column by column

Usage

the easiest usage requires to include the library, instantiate the class and call the method SendFile() which does all the job

require($your_path.'php2mat.php');
$php2mat = new php2mat();
$my_array = array(
    "magic"=>array(1, 0, 9, 3, 7, 6),
    "a_really_very_very_long_variable_name"=>array(array(1, 2, 3, 4, 5, 6),array(1, 0, 9, 3, 7,6))
);
$php2mat->SendFile("test.mat", $my_array, "<my_text>");

An other typical use case is extracting data from database MySQL and saving into MAT file bunch by bunch, this method consumes much less memory than using $php2mat->SendFile() after having loaded all data.

require($your_path.'php2mat.php');
$php2mat = new php2mat();
$php2mat->php2mat5_head('test.mat', "<my_text>");
$res = mysqli_query($db, 'SELECT value1 FROM table');
$php2mat->php2mat5_var_init('variable_name', 2, mysqli_num_rows($res));
while ($row = mysqli_fetch_array($res, MYSQLI_ASSOC)) {
    $php2mat->php2mat5_var_addrow($row['value1']);
}
$res = mysqli_query($db, 'SELECT value2 FROM table');
while ($row = mysqli_fetch_array($res, MYSQLI_ASSOC)) {
    $php2mat->php2mat5_var_addrow($row['value2']);
}
