I get an error message trying to use polyroots: this value must be a scalar.
It seems to me, that the exact same error is also in the Quicksheet (see image).
Any hint would be appreciated.
Thanks a lot
Solved! Go to Solution.
No, the quicksheet is not wrong and o.svahn has shown exactly whats in the quicksheet,
I am not sure what went wrong on your side, but when I open the quicksheet it works perfectly OK:
you are right. In fact the answer of @o.svahn appeared to me too identical. But the fact is that I deleted the appropriate lines, typed them again (I do not use coeffs, I just define the vector myself) and then it worked.
And now if I start from scratch MathCAD and go to the help and then open the quicksheet, it does not show the error anymore. Fortunately I documented it 😁 or someone could think I dreamed the problem!
The exact sequence is this: I looked at the help (only), typed the requested instructions in my worksheet, it gave the error "this should be a scalar", then I went to the help and opened the quicksheet and I had the same message in it. !!
Possibly a "corrupted" session.
No matter what, now it is working perfectly. Sorry for disturbing everyone!
