Given/Find command, variable not defined

[jpromol]

Hi all,

I'm trying to solve a system of equations of motion using the given and find commands in Matlab.

However I get a variable undifined error on the find command and I cannot figure out why.

See the attached worksheet for my attempt.

Can anyone figure out what I'm doing wrong?

Fi is your problem. You've written it as though it's another component of F, along with F1, F2 etc.. If this was intended then i needs to be a pre-specified integer.

Thank you!

You're right I can't belief I've not seen this myself...

It works now.
