The problem is that you are defined the h matrix as constant matrix (no
derivative information) when you created it in the data section.
When you attempted to assign values in it to equal values of a parameter
the complaint occurs. Basically you are not supposed to let
variables created in the data section depend upon parameters, which is
what you are doing. You really do not want to be doing this even if
it were allowed because presumably you are putting the parameters into
your matrix so you can use your matrix in calculations of your objective
function, and admb needs the derivative information in order to use its
search approach for the minimum. Basic rule. If a variable
changes when the parameter values change it should be defined in the
parameter section and not the data section.<br><br>
Solution is easy. Define h_f in the parameter section just by
moving the line of code you now define it with from the data
section.<br><br>

I am getting a g++ error message when trying to compile my ADMB code. I
get an error saying it cannot convert 'param_init_bounded_number' to
'double'<br>
The simplified version of the code causing the error message is<br><br>
for (int i=1;i<=25;i++)<br>
{for (int j=1;j<=90;j++)<br>
{if (i<=11) <br>
{h_f(j,i)=b96}}}<br><br>
In the data section I have a dummy matrix for h_f<br><br>
matrix h_f(1,90,1,25)<br><br>
And in the parameter sections I have b96 as a bounded number with the
initial value of 0.82 being read in from the starting estimate
file.<br><br>
init_bounded_number b96(0,1)<br><br>
Does anyone know why I might be getting this error message?<br><br>
Thanks,<br><br>
