I'm trying to do comparison of two matrices. I'd like a bool result. The code I have feels hacky, and suspect there is a much cleaner way. Thank you for any help!

typedef Eigen::Array<bool, Eigen::Dynamic, Eigen::Dynamic> ArrayXb;

TEST(hammimg, generator_matrix)
{
ArrayXb correct_gm(4,7);

// here is what we are testing against
correct_gm << 0,1,1,1,0,0,0,
1,0,1,0,1,0,0,
1,1,0,0,0,1,0,
1,1,1,0,0,0,1;

// in the generator we we create the generator matrix
Hamming ham(parity_bits);

// hack starts here. I use a resultant matrix for the == operation
// and make sure it is all ones....
ArrayXXb all_ones(4,7);
all_ones = correct_gm == ham.generator_matrix;
ASSERT_EQ(true, all_ones.isOnes());
}

The best is to use .all():

Code: Select all

assert( (correct_gm == ham.generator_matrix).all() );
