In most applications, it is primary square roots that are of interest and simplicity, virtually all the existing theory and available methods are for such square roots [10]; thus, we will concentrate on primary roots in this paper. There are more sophisticated counting techniques based on the same . Http://www.research.att.com/~njas/hadamard/; Hadamard matrices and their applications, by K. I believe this is a well-known proof for showing that the Hadamard matrix has rigidity function n^2/r, and it is due (in unpublished form) independently to Grigoriev and Nisan (over ten years ago). To the “Cardano's Rings” puzzle (which apocryphally dates back to 2nd-century China, but is described in print by Luca Paciolli circa 1500); used for telegraphy by Emile Baudot in 1878; described in a 1947 patent application by Frank Gray. Codenotti (Matrix Rigidity, Linear Algebra and its Applications, 304(1-3):181 192. Also, numerical solutions of .. Hadamard Matrices and Their Applications (Lecture Notes in Mathematics) by S. A Hadamard Matrix: Such a matrix was invented by James Sylvester in 1867, who called it the wonderfully complex name, an “anallagmatic pavement”—here “anallagmatic” refers to the matrix being virtually its own inverse. Even in a low-level survey paper by B. Circulant matrices and their generalizations arise in many areas of physics, electromagnetics, signal processing, statistics, and applied mathematics for the investigation of problems with periodicity properties [1–3].
