UPDATE: got the final error fixed by just actually replacing operator[] with this->operator[].
UPDATE 2: logic_error fixed! _P error is all that's left! (which only shows up in DUE, not UNO or other boards...)
UPDATE 3: Changing the name of the temp matrix to _Pt worked, might have been a reserved macro?
NEW ERROR:

/Users/zackbright/Documents/Arduino/libraries/StandardCplusplus-master/func_exception.cpp: In function 'void std::__throw_bad_alloc()':

Error compiling.
Looks like I need to use -fexceptions...
This report would have more information with "Show verbose output during compilation" enabled in File > Preferences.
There's a lot here, but I'm hoping that giving everything is what I ought to do to get a good answer to this.
using Arduino 1.6.1 for arduino DUE on OSX.
using this library to get std namespace 'https://github.com/maniacbug/StandardCplusplus/'
And this is the library I am having trouble compiling: 'http://kalman.sourceforge.net/index.php'
I have moved around the filter library into this format to be able to use it fr arduino, and now have been able to at least do an include without it not finding the header files:
As you can see I had to rename the files to .h headers (not sure how necessary this really was), and rename the folder to the same title as my .cpp and .h, and of course edit all the enclosed files to reference files differently: example
#include "kalman/ekfilter.hpp"
//the "kalman/" is because these used to be in a separate include folder
is now this instead:
#include "ekfilter.h"
So, now, when I just try to compile:
#include <StandardCplusplus.h>
#include <ekfilter.h>
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
I get this mess of errors shown below.
The first error is really driving me nuts, because this StandardCplusplus library should handle the std:: namespace, and there isn't anything I can ostensibly find wrong with the implementation in that codebase.
From what I see, most of anything following _P is an issue that that first error prevents casting the _P variable as a matrix as defined in kmatrix.h. Weirdly enough, and this may point to a solution, these errors do NOT show up when I compile for Arduino UNO.
The last pair of errors I'm just unclear honestly what it even means.

So there's a lot to fix here, but this is all after I fixed some issues with the way the library was formatted already:
I had to add -fpermissive to "/boards.txt" compiling preferences
there was a weird implementation in their code that wouldn't compile, I changed this:
// These are explicitly GNU C++ specific.
// This is the exception class we report -- "GNUCC++\0".
const _Unwind_Exception_Class __gxx_exception_class
= ((((((((_Unwind_Exception_Class) 'G'
<< 8 | (_Unwind_Exception_Class) 'N')
<< 8 | (_Unwind_Exception_Class) 'U')
<< 8 | (_Unwind_Exception_Class) 'C')
<< 8 | (_Unwind_Exception_Class) 'C')
<< 8 | (_Unwind_Exception_Class) '+')
<< 8 | (_Unwind_Exception_Class) '+')
<< 8 | (_Unwind_Exception_Class) '\0');
to this:
const _Unwind_Exception_Class __gxx_exception_class = "GNUCC++\0";
