Help with Mathcad Rkadapt function!

  1. Jul 16, 2007 #1
    1. The problem statement, all variables and given/known data

    I'm trying to use the rkadapt function in mathcad 13 but it's coming up in red and telling me 'This function cannot be used here'. Not really sure why because all the constants used have been defined above it and take sensible values. The values of x1 and x2 have been defined in the matrix x. If anyone can help me with this that would be great! :cool:




    2. Relevant equations

    Hello!!

    I have the same problem... Natty, did you find an answer to the problem?
    (I have used the Rkadapt function in Mathcad 2000 and it worked just fine, but in Mathcad 13 i don;t know what the problem is :( ...)

    Thx!!

    Hey johnny, I've got mine working now but I still don't know what was wrong with it originally! I started a new worksheet and re-wrote it which seemed to do the trick, not sure why because all the positioning and declarations were exactly the same.... Sorry I can't provide a more helpful answer!
