Matlab scripts calling user-defined functions

[Izzyschall]

Hi

I'm trying to run within labview a matlab script which calls fsolve, which requires a user defined .m function to be supplied to fsolve.

While the script runs well in matlab, it will not execute at all in labview - I get error 1050, with the error message 'Error using ==> feval Undefined function or method 'eqns' for input arguments of type double'. I suspect this is because the matlab script server cannot locate the eqns.m file i am using, but after setting all paths to include the location of my eqns.m file it still doesn't work. Any Ideas?

Where did you set the paths? In the Matlab IDE, or in your Matlab Script Node? When you open a VI that uses the Matlab Script Node a Matlab command window pops up. Type "path" in that window to see what directories are contained in the matlab search path.
