CRYSTALS contains a simple calculator for processing 3x3 matrices. Two
matrices, A and B, can be input and operated on. The result is output to
the screen and left in an accumulator. It can be transfered to A or B
for further operations. There is currently no interface to any stored
crystallographic information.
Followed by the nine values for the matrix A by rows
Followed by the nine values for the matrix B by rows
Accumulator = AxB
Accumulator = A'xB
Accumulator = AxB'
Accumulator = A'xB'
Accumulator = A'
Accumulator = A-1
Accumulator = Eigenvectors of A
Matrix A = Accumulator
Matrix B = Accumulator
