All these functions can be applied to scalar value. All but transpose and
|
|
5
|
hermitian can be also applied as element-wise operations on vector, matrices
|
|
6
|
inputs. transpose and hermitian are applied on vector and matrices as regular
|
|
7
|
(non element-wise) operations.

The Lustre library provides only scalar functions for all cases, and, in the future,

|
the matrix versions of them.

For the moment, we focus only on theoretical types: real, complex.

A future version can be specialized for concrete datatypes (single, double,

(u)intXX).
