Hey guys, i`ve started in to a Masters and im having a few problems with numerical Algebra. I understand the fundamentals but we ve been giving a project which requires us to use matlab- and there my main problem arises. Ive never used matlab till this course, only maple and alot of it is going over my head. Ill list the question here and if any of you guys could give any help or direction i really would appreciate it!!!Consider the following class of singularly perturbed problemsAny help with particular reference to the matlab code would be like gold!! Thanks in advance I was asked to examine the numerical performance of different numerical methods applied to these problems, namely Explicit, implicit and centred differencing. I have discuss the stability of these schemes and make a plot of unstable output and pf stable output.

The fitting method in this paper by Daniel Duffy might be helpful.

These SP have been done by them.Traditional FDM is not robust for Sp problems P.S. are you in Dublin by any chance?

Thanks guys for the help!!!The 2 articles are a good help, Yeah Cuchulainn im in dublin, Prof. O` riordan`s course; genuinely very interesting but my programming skills are less than apt hence my `appeal for help`

It is only logical. Learning it on your own just takes too long.
