As a generalization of a Hadamard matrix, a c-matrix is a square matrix with one entry 0 and all other entries -1 or 1 in each row. With each row being pairwise orthogonal. Show that the transpose of a c-matrix is a c-matrix.

I can visualize why this true but I'm not sure how to go about proving this.

You can turn the matrix into an orthogonal matrix by normalizing rows appropriately. Then argue from there...
