I am trying to use the euler and then midpoint method to solve for a value. I call on a different mfile that I have named "dydtsys.m" where I gather the equations needed for this project. Any and all help would be appreciated. I have tried to rename the 'unrecognized function or variable' as euler, eulsys, eulersys.

maybe you need copy the function eulsys.m in your system. In this link you have a copy:

So should I establish a separate mfile with one of those and then call on it by replacing the eulsys with @eulfun or just change it to eulfun
