Detailed Description

Sanity check tests for some CUDD functions.

testcudd reads a matrix with real coefficients and transforms it into an ADD. It then performs various operations on the ADD and on the BDD corresponding to the ADD pattern. Finally, testcudd tests functions relate to Walsh matrices and matrix multiplication.
