I'm really confused about what's going wrong with my call to FindInstance
:
FindInstance[MatrixRank[{{0, 1, 1}, {1, 0, 1}, {(-1)^i1, 1, 0}}] == 3,{i1}, Integers]
{{i1 -> 33}}
The matrix {{0,1,1},{1,0,1},{-1,1,0}}
has rank 2. Also when I repeat the above call with the MatrixRank
function set equal to 2, FindInstance
returns {}
. What am I missing??
MatrixRank[{{0, 1, 1}, {1, 0, 1}, {(-1)^h, 1, 0}}]
orMatrixRank[{{0, 1, 1}, {1, 0, 1}, {h, h, h}}]
