Detailed Description
the variable is either simple-variable and nr_ is the index in vector of parameters, or it is "compound variable" and has nr_==-1. third special case: nr_==-2 - it is mirror-variable (such variable is not recalculated but copied) In the second case, the value and derivatives are calculated:
- string is parsed by eparser to VMData representation, and then it is transformed to AST (struct OpTree), calculating derivates at the same time (calculate_deriv()).
- set_var_idx() finds positions of variables in variables vector (references to variables are kept using names) and creates bytecode (VMData, again) that will be used to calculate value and derivatives.
- recalculate() calculates (using run_code_for_variable()) value and derivatives for current parameter value
