Currently the implementations of BiCGStab and GMRES use methods in LinearAlgebra that do not have generic fallbacks.
BiCGStab makes an explicit call to `BLAS.gemv!` which is implemented only for r…

I have tested the is_normalized() function with two normalized dual quaternions, dq1 and dq2, but it only returns False. The two dual quaternions:
`dq1 = DualQuaternion(-0.19846574648301676, -0.00…

The approved API is here: https://github.com/dotnet/runtime/issues/24168#issuecomment-642847557
Due to the size of the approved surface area, it is being split into multiple sections for people who…

Thanks for your great work!
There might be a small error in the calculation of root_rot_velocity.
In the original version, it is calculated through qmul function:
`r_velocity = qmul_np(r_rot[1:]…

作者大大我看代码发现主要变动在imuconvert中对RPY改为单位矩阵，而在后面transformupdate中与磁力计数据按照权重融合时候并没有关掉这个融合，这个RPY的单位阵不会有影响吗

Overflow or underflow occurs when the divisor is a giant or minute number in quaternion and octanion division.
The following code, which is expected to yield 1, unexpectedly yields NaN.
```cpp

hello, What is the meaning of the variable 'can_bus' name?
In actual operation, the following phenomena are observed. After the four properties of the quaternion are assigned to the array, only the…
