sgolayfilt warning

kmos opened this issue · comments

In a normal execution of navego_example.m, I receive a warning in gyro_gen:

Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 5.892434e-33.

In sgolay (line 101)
In sgolayfilt (line 71)
In gyro_gen (line 43)

is it normal?

Dear kmos,

Thank you very much for pointing out this issue.

According to me, this is not an error but it is not an elegant solution neither.

I adjusted both parameters in sgolayfilt(), the polynomial order K and the frame size F to avoid this warning.

Regards.
