Help me:matlab program

[damia]

hello..i'm damia
i need help in matlab programming :confused::eek3::confused:
my project is on delay time modelling for complex system using maximum likelihood estimation. i already program it, but i think the estimated value is not correct.and i think that it is because of the coding...huhuhuuu~~~
if anyone can help me, i try to give the program that i have done and just contact me at cemot_comey@yahoo.com
