Member Function Documentation

add()

void add ( float &  x, float &  e, float  x1, float  e1  )

inline

Add (x1, e1) to (x, e) using weighting by errors (e.g.

least square fit of a constant)

Parameters

x	input/output value
e	input/output error
x1	value to be added
e1	error to be added

Definition at line 73 of file ValidationTreeStruct.h.

        e = e1;

      }
      e *= e;
      e1 *= e1;
      float s = 1 / e + 1 / e1;
      x = (x / e + x1 / e1) / s;
      e = sqrt(1 / s);
    }

merge()

void merge

(

const ValidationTreeStruct &

other

)

Merge two structures.

Parameters

other

structure to be merged with this one
