RE: [eigen] Assertion error on eigen_assert(checkIndexRange(indices))

[Nuno Marques <n.marques21@xxxxxxxxxxx>]

Forget this! Sorry stupid error and already solved:

https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp#L1200-L1201

The index should just go till 2, not 3! That's why it was giving an assertion error.

Anyhow, there are still the includes to correct :)

Thanks once again to the dev team, specially to Christoph!

Best regards,

Subject: [eigen] Assertion error on eigen_assert(checkIndexRange(indices))
Date: Tue, 18 Aug 2015 16:04:18 +0100

Hi there guys,

I'm using some Tensors on a Nuttx OS, and I'm getting an assertion error:

Assertion failed at file:/home/nuno/dev_px4/apply_eigen_math/Firmware/src/lib/eigen/unsupported/Eigen/CXX11/../../Eigen/CXX11/src/Tensor/Tensor.h line: 233

Line 233 is part of an inline function:

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Scalar& operator()(const array<Index, NumIndices>& indices)

{

eigen_assert(checkIndexRange(indices));

return coeffRef(indices);

}

What I'm trying to understand is where is this assertion failing. The code I have and where I'm using Tensors is: https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp, where I created the following Tensors:

Tensor<float, 3> est_buf(EST_BUF_SIZE, 3, 2); // estimated position buffer

Tensor<float, 3> R_buf(EST_BUF_SIZE, 3, 3); // rotation matrix buffer

Those are modified in:

https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp#L822-L830

https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp#L838

https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp#L1187-L1192

https://github.com/TSC21/Firmware/blob/apply_eigen_math/src/modules/position_estimator_inav/position_estimator_inav_main.cpp#L1195-L1203

Can any of the developers help understand why is it giving an assertion error? 

Thanks in advance! Best regards,
