- for cases where a 3D tensor is being used to represent 2D content,
the determinant is zero. Can use inv2D(excludeDirection) to compensate
and invert as if it were only 2D.
ENH: consistent definitions for magSqr of symmTensors, diagSqr() norm
COMP: return scalar not component type for magSqr
- had inconsistent definitions with SymmTensor returning the component
type and Tensor returning scalar. Only evident with complex.
- vector, tensor versions are defined component-wise
to avoid intermediates.
The base version uses the form "(1-t)*a + t*b" without any bounds
checking (ie, will also extrapolate).
ENH: define addition/subtraction operations for scalar and complex
- required since construct complex from scalar is explicit
- additional tests in Test-complex
- operators are still incomplete, as are dimensioned fields,
field-fields etc.
- split complexFields into separate complexField, complexVectorField files
- add construction from and conversion to std::complex, which allows
easier wrapping of functions
- add Foam:: functions for complex versions of sin, cos, ...
- was historically defined as (1 1), but it is more consistent with
the concept of one to have a real component only.
Now defined as (1 0): 1+0i
STYLE: remove obscure '!' operator for complex conjugate
- either use the member function or the '~' operator
