Allow passing an initial partial Schur decomposition #143

Closed haampie closed 7 months ago

haampie commented 7 months ago

This commit allows users to

  1. avoid allocations by reusing existing arrays/buffers
  2. specify custom matrix types for V, H and temporaries
  3. starting the algorithm from an existing partial Schur decomposition

by exporting ArnoldiWorkspace, which holds the major arrays, and partialschur!(A, ::ArnoldiWorkspace; ...).
