one question about the function-sqp in Octave

[Yanbao Zhang]

Hello everyone, 

I am a beginner of Octave. I read Octave FAQ on the website, but I still cannot 
figure out how to solve the following problem when I run the function 
[x,obj,info,iter,nf,lambda]=sqp(x,objf,[],cif,[],[],100,1e-50)(PS:I have two 
similar programs. No such problem for the first program but for the second one.)

error: EIG: matrix contains Inf or NaN values
error: evaluating if command near line 268, column 5
error: evaluating if command near line 84, column 3
error: called from `qp' in file 
`/usr/local/share/octave/3.0.0/m/optimization/qp.m'
error: evaluating while command near line 359, column 5
error: evaluating if command near line 195, column 3
error: called from `sqp' in file 
`/usr/local/share/octave/3.0.0/m/optimization/sqp.m'

Do you have such similar experience,and could you give me an explain? Thank you 
in advance!
