# matr

Orient the structure along cell axes

[1,2,3 or abc] or [abc a1b1c1] or [x11 x12 x13 y11 y12 y13 z11 z12 z13]

Orientates the model along; a (1 or 1 0 0), b (2 or 0 1 0), c (3 or 0 0 1) or any other crystallographic direction e.g. 123, which sets the current normal along the $(1 \times a+2 \times b+3 \times c)$ vector. Two crystallographic directions (from and to) may be specified to align the current view normal along the (to-from) vector. Also a full Cartesian matrix can be specified. If the directions are signed or consist of multiple digits, all components should be of the same length like in 1 2 0 1 0 1 or -1 +1 +1 (same as -1 0 1 0 1). If no Arguments are given, the current Cartesian orientation matrix is printed.

• -r: uses the reciprocal lattice instead of the direct.

>>matr 1 or >>matr a or >>matr 100 - sets the current normal along the crystallographic a direction. >>matr 100 011 sets the current normal along the (0 1 1 -- 1 0 0) direction (the normal direction changes if from and to are swapped)
