Re: how to solve this error mesages from this program?

[Doug Stewart]

 I am very thankful to many good guidnances from Nicholas and others for the

problem of symbolic.
By the way, the next problem is to run this program  RBCkato.m

Thank you very much! That is perfect graph. I should follow your corrections and try it tomorrow! Thank you for your great corrections! Insang 

I had one mistake.

Here are the new plots

https://www.dropbox.com/s/t0dchexk9nczspv/rbc1.jpg?dl=0

I had to change 

coef = eval(jopt);

to 

  fh=function_handle(jopt)

  coef=fh(cstar,cstar,kstar,kstar,lstar,lstar,vstar,vstar) 

also change

  coy  = eval(jy);

to

       fh2=function_handle(jy)

      coy=fh2( kstar,lstar,vstar)

    

 @ Colin Macdonald

 There seems to be a problem with the eval() function when it is used with

the results from a symbolic calculation.

 The function given above calculates a symbolic matrix which it is

then trying to convert it to a numeric answer. I tried to use double instead of

eval but it still did not work. I then tried subs() to convert each symbolic symbol 

to a number and that also failed. In the end I had to convert it to a function_handle

and then evaluate it at the given values. 

Should the eval function work for this case?
