Released on 01/12/2008:
• | YADA now has 3 reserved parameter names, "YADAg", "YADAh", and "UserVariables". The first two are used to temporarily swap the names of the g and h matrices in "compute_aim_matrices" before searching for parameters. The third is now viewed as a field in the ModelParameters structure that YADA sets up. This field is reserved for passing information to and from the user defined functions for handling parameter functions. Such information may be used when solving the steady-state numerically within an update parameter function (it may,e.g., contain initial values that is used by fsolve). The field "UserVariables" can itself be a structure with arbitray field names. YADA simply doesn't regard this name as a parameter name. |
