# MATNORMALHERMITIAN

a matrix that behaves like (A*)’*A for `MatMult()` while only containing A

## Developer Notes

This is implemented on top of `MATSHELL` to get support for scaling and shifting without requiring duplicate code

Users can not call `MatShellSetOperation()` operations on this class, there is some error checking for that incorrect usage
