In the square case, a master Hadamard matrix is a complex Hadamard matrix arising from the master-function construction, and $F_N$ denotes the Fourier matrix of order $N$. A Dic tu…

A regular matrix $H\in M_N(\mathbb C)$ is a complex Hadamard matrix whose row scalar products decompose as sums of cycles, and an affine deformation is the deformation notion used…
