## Function Documentation

 CompMap cyclus::compmath::Add ( const CompMap & v1, const CompMap & v2 )

Does component-wise subtraction of the nuclide quantities of v1 and v2 and returns the result.

No normalization is done. Example:

v1[922350000] = 2.3;
v1[922380000] = 1.3;
v2[922350000] = 1.1;
v2[922380000] = 1.2;
// v3[922350000] == 3.4, v3[922380000] == 2.5

## ◆ AllPositive()

 bool cyclus::compmath::AllPositive ( const CompMap & v )

Returns true if all nuclides in v have quantities greater than or equal to zero.

Definition at line 83 of file comp_math.cc.

## ◆ AlmostEq()

 bool cyclus::compmath::AlmostEq ( const CompMap & v1, const CompMap & v2, double threshold )

Returns true if all nuclides of v1 and v2 are the same within threshold.

No normalization is performed.

Definition at line 93 of file comp_math.cc.

## ◆ ApplyThreshold()

 void cyclus::compmath::ApplyThreshold ( CompMap * v, double threshold )

All nuclides with quantities below threshold will have their quantity set to zero.

Definition at line 45 of file comp_math.cc.

## ◆ Normalize()

 void cyclus::compmath::Normalize ( CompMap * v, double val )

The sum of quantities of all nuclides of v is normalized to val.

Definition at line 63 of file comp_math.cc.

## ◆ Sub()

 CompMap cyclus::compmath::Sub ( const CompMap & v1, const CompMap & v2 )

Does component-wise subtraction of the nuclide quantities of v1 and v2 and returns the result.

No normalization is done.

Definition at line 27 of file comp_math.cc.

## ◆ Sum()

 double cyclus::compmath::Sum ( const CompMap & v )

Sums the quantities of all nuclides without normalization.

Definition at line 36 of file comp_math.cc.

## ◆ ValidNucs()

 bool cyclus::compmath::ValidNucs ( const CompMap & v )

Returns true if all nuclide keys in v are valid.
