Member Function Documentation
◆ deriv()
|
pure virtual |
total derivate with respect to a variable, which is a function of the stock variables.
- Parameters
-
sv - stock variables fv - flow variables (function of stock variables, computed by eval) ds - derivative of stock variables df - derivative of flow variables (updated by this function) n - size of df array
To compute the partial derivatives with respect to stock variable i, seed ds with 1 in the ith position, 0 every else, and initialise df to zero.
Implemented in minsky::ScalarEvalOp.
◆ eval()
|
pure virtual |
evaluate expression on sv and current value of fv, storing result in output variable (of fv)
- Parameters
-
n - size of fv array
Implemented in minsky::ScalarEvalOp.
◆ setTensorParams()
|
inlinevirtual |
◆ throw_error()
|
inline |
in1 - indices describing input 1's vector in2 - indices describing input 2's vector (if double op) in2b/interp - interpolation support: out[i]=op(inp[in1[i]], interp*inp[in2[i]]+(1-interp)*inp[in2b[i]])
