symmetry-operations-symbols

Haskell Derivation of symbols and coordinate triplets Library

Quickstart

Make new stack project and move to project directory.

% stack new symopRepl
% cd symopRepl

Edit extra-deps part of stack.yaml like below.

extra-deps:
- matrix-as-xyz-0.1.1.1
- symmetry-operations-symbols-0.0.1.1

Then start repl.

% stack repl

Setup packages and load modules.

-- prepare
repl> :set -package hall-symbols
repl> :set -package symmetry-operations-symbols
repl> :m Data.Matrix.AsXYZ Data.Matrix.SymmetryOperationsSymbols

Use like below.

repl> fromMatrix' . fromXYZ $ "x,y,z"
" 1 "

repl> fromMatrix' . fromXYZ $ "-x,-y,z"
" 2  0,0,z"

repl> fromMatrix' . fromXYZ $ "-y,-x+1/2,z"
" g (-1/4,1/4,0) x+1/4,-x,z"
