??? undefined function or method 'ga14bus_29_sep_2018' for input arguments of type 'double'.

dear sirs how can i solve this problem in matlab 2009b

[Walter Roberson]

Note: you marked the question has having to do with Extended Symbolic Math Toolbox, which was a toolbox that was no longer available in the MATLAB release you indicate you are using, R2009b.

You do not appear to be using any function from the Extended Symbolic Math Toolbox: generally speaking those would show up as calls to maple() or evalin(symengine) or feval(symengine)

cos =ga14bus_29_Sep_2018(par) undifine

[Walter Roberson]

You do not define a function with that name

[tahseen alshmary]

how can i define it

[Walter Roberson]

   function cost = ga14bus_29_Sep_2018(par)
     cost = randn(size(par));
