Can i trasform a complex double into euler representation
显示 更早的评论
Hi to everyone , I'm working with a kalman filter for heading estimation . I'm using quaternion for estimating the orientation . At the end of the execution i have a complex double quaternion data and I can't to trasform into euler representation.

Can you use abs and angle?
>> a = -14.6566171621163 + 0.495320247582976i;
b = -0.459846284143683 + 0.100914051723435i;
c = -6.39252310373873 - 0.0494395243698083i;
d = -2.56597822306176 + 0.475119224468788i;
M = [a;b;c;d];
Mp = [abs(M) angle(M)]
Mp =
14.6650 3.1078
0.4708 2.9256
6.3927 -3.1339
2.6096 2.9585

abs(a+bi) = sqrt(a^2 + b^2) i.e it's the magnitude
a+bi = abs(a+bi)*exp(i*theta) where theta is angle(a+bi)
