public BiCG(Vector template)
- Constructor for BiCG. Uses the given vector as template for creating
scratch vectors. Typically, the solution or the right hand side vector
can be passed, and the template is not modified
- Parameters:
template
- Vector to use as template for the work vectors needed in the
solution process
