make _normalize_matrix_blocks check number of orbitals Closes #346 See merge request kwant/kwant!349

This test was previously incorrect, but because we didn't actually check the number of orbitals on constant values on finalization this was not caught.
-
Joseph Weston authored
We allow the function that produced the data to be passed to '_normalize_matrix_blocks', and any error messages are augmented with this information. This may prove useful for debugging.

Previously these 2 steps were done in one pass. Now we separate them out in order to facilitate augnmenting the verification to include checking the number of orbitals (in future commits).

Joseph Weston authored
These will be needed later when verifying that constant values have the correct shape.

It is only used in the tests anyway. This way we export less API from the builder module.

add a test for invalid value functions See merge request kwant/kwant!347
-
Joseph Weston authored
Previously we would use '*_term_parameters', as returned by '_make_*_terms', however this was polluted with Exceptions. Instead we modify '_make_*_terms' so that it does not return this confusing object and use 'terms' directly, which are guaranteed to either have a valid set of 'parameters' or 'None'.
-
Joseph Weston authored
Note that we only raise an error if 'params' is specified. This may actually be incorrect; if we have a keyword-only parameter, for example then the way in which we call the value function will always produce an error, regardless of whether 'params' is specified or not.

implement vectorized value broadcasting Closes #342 See merge request kwant/kwant!346

This is shorter but no less clear.

Joseph Weston authored
When a value function returns a single scalar or a matrix, we reshape and repeat this value to obtain the required 3-axis array.
-
Joseph Weston authored
We want to enable: single scalars (norbs=1) or matrices (norbs>1), functions returning single scalars or matrices, or functions returning vectors of single scalars or matrices.

It is very easy to accidentally modify the subgraphs in place, which should not be possible

Joseph Weston authored
Finalized Builders store negative term numbers associated with edges in the graph whose reverse we must compute using 'hamiltonian_term'. If we are not careful people may use these negative term numbers with 'hamiltonian_submatrix'.
