A problem in your test method

[mrchipset]

Hello,
I think you make a mistake in your function return value arrange in Line 167. Your code is x, f, cost = beads(y=sig, d=d, fc=fc, r=r, lam0=lam0, lam1=lam1, lam2=lam2). But refer from the definition in Line 101, it should be x, cost, f = beads(y=sig, d=d, fc=fc, r=r, lam0=lam0, lam1=lam1, lam2=lam2).

Yes, you are right!
In line 167, the test is not correct, and I will amend this, thank you!
