arduino:sam support

Hello, I am trying to use this library with an Arduino Due, based on 32-bits ARM Cortex-M3 (SAM core).

Have this library been tried with Arduino Due before? Would be really helpful if support could be added.

I get the following error:
error: #error THIS PLATFORM IS NOT SUPPORTED BECAUSE THERE IS NO STANDARD LIBRARY

Compiling with:
arduino-cli compile --fqbn arduino:sam:arduino_due_x_dbg sketch.ino -v

Compatible Boards

This library will only compile for Teensy 3.0 to 3.6. However, it will not compile for Teensy 4.0 or higher. Compiling for 4.0 or higher gives me the following error:

Fixed compile issue by commenting out __FlashStringHelper in ArduinoEigenCommon.h.

Read me, does not list the compatible platforms

Please update your read me to include a list of what platforms this library can compile for, you only list the platforms that it’s not compatible for.

Asser Error when trying to initialize large size vector with less values initialized

  VectorXd acc(2000);
  acc.setZero();
  acc << 1,2,3,4,5,6,7,8,9,10;
  double maxVal = acc.maxCoeff();
  double minVal = acc.minCoeff();
  double meanVal = acc.mean();

  Serial.printf("Max value: %f\n", maxVal);
  Serial.printf("Min value: %f\n", minVal);
  Serial.printf("Max mean: %f\n", meanVal);

I have initialized acc vector with size of 2000. I have taken max size as there is no way to increase the vector size dynamically by push as this will cause heap fragment issue.

I get this error when i try to do it.
assert failed: XprType& Eigen::CommaInitializer<MatrixType>::finished() [with XprType = Eigen::Matrix<double, -1, 1>] CommaInitializer.h:124 (((m_row+m_currentBlockRows) == m_xpr.rows() || m_xpr.cols

Initializing the values like this works

acc(0) = 1;
acc(1) = 2;
acc(2) = 3;
acc(3) = 4;
acc(4) = 5;
acc(5) = 6;
acc(6) = 7;

But it gives wrong output for mean() function as it divides it by 2000 elements.

Output:

Max value: 7.000000
Min value: 0.000000
Max mean: 0.014000

Crash when initializing matrix of size 170x170

I've observed that creating a very large matrix causes the ESP32 to crash. I was able to replicate this issue by creating a new PlatformIO project and attempting to create a matrix of size 170x170. This resulted in a crash of the ESP32. However, creating a matrix of size 169x169 does not cause a crash, and there is still a significant amount of heap memory available.

Free heap memory: 200308 bytes n = 169
Free heap memory: 201656 bytes n = 168
Free heap memory: 202996 bytes n = 167
and so on.

So I guess ArduinoEigen/ArduinoEigenCommon.h should also undef D0, D1, D2, D3.

Additionally, in the past, I am quite sure I saw conflicts with A0 and A1 (I don't remember on which board). So you might want to also undef A0 and A1 to be on the safe side.
