Phonopy primitive axis
http://phonopy.github.io/phonopy/examples.html WebWhere supercell_matrix defines the supercell expansion used to calculate the force constants using the finite displacements method, and primitive_matrix (optional) defines the primitive cell axis matrix. If primitive_matrix is not defined, identity matrix is used (primitive cell = unit cell). 2b.

WebThe present invention is to determine abnormalities of organs or muscles in the body. A method for determining abnormalities in organs or muscles in the body comprises the steps of: acquiring at least one image for organs or muscles in the body; determining at least one characteristic matrix for the at least one image; determining a specific value for … WebThe trigonal crystal system is defined by a three-fold rotation axis, and can be generated from the cubic crystal system by stretching the cube along its diagonal. The symmetry requires the primitive vectors to have the form a = b, α = β = π/2, γ = 120∘.
