help with program that doesn't plot

I have this program that doesn't plot, but is taken from another one that works perfeclty. Can you help me please?

Karla - please format the above code so that is is readable. Or, attach the code to your question using the paperclip button. As well, please explain or describe any errors that you are observing. You state that this program doesn't plot - what does that mean exactly? No plot appears, or it appears incorrectly, or..?

    %%%function A1pos = TestStatistic 
function ne(Isource,b)
function A1pos = DegradationStatistic

For starters, you've got two function statments; in an m-file this would end up w/ an empty function ne assuming the file were named ne.m and a second internal function DegradationStatistic which isn't accessible to anything outside the file. (ASIDE--) As far as Matlab cares, the function name inside the m-file is immaterial in referencing/resolving the function; it's only the m-file name that matters. Hence, whatever it is that the file is called is what the interpreter thinks the function is; I just used ne above as that's the first function statement in the posting).

To compound matters, you've aliased the builtin function ne which is a basic operator "not equal" or "~=" which will cause all sorts of other grief.

So, first, fix these problems...

a) Eliminate the 'ne' function name -- probably the whole line should just be deleted from the file but if there's intended some function with that prototype you _must_ rename it to a non-TMW function,

b) the *DegradationStatistic* function should then be in its own file _DegradationStatistic.m_ (altho I personally dislike the CamelCase naming convention, that's your call)

I'm guessing that you're trying to execute DegradationStatistic and it's not being found owing to the above formatting in the file that makes in an internal function.

[Guillaume]

Slight correction to dpb comment, the file should be named DegradationStatistics.m as that's the name of the function. A1pos is the return value.

Matlab normally warns about wrongly named files and offer to rename them for you.

As others have said, something more descriptive than 'it doesn't work' would get you more help. Also have you tried to step through your function with the debugger to see what's it doing?

Good catch, Guillaume, just glanced up and typed the first thing I saw... :) Fixed in the posting...
