Complete Function list |

The class **S2Grid** is used in MTEX to store the set of specimen directions organized in a pole figure. Of central importance is also the plotting method of this class since it is used by almost all other plotting methods in
MTEX to perform spherical plots.

There are various ways to define a S2Grid. Next, you find some examples. For a detailed description of possible specifications look for the documentation of the constructor S2Grid.

% equidistributions S2G = equispacedS2Grid('points',100,'antipodal'); % specified by number of points S2G = equispacedS2Grid('RESOLUTION',5*degree,'antipodal'); % specified by resolution % regular grids S2G = regularS2Grid('points',[72,19]); % specified by number of theta and rho steps S2G = regularS2Grid('theta',linspace(0,2*pi,72),... 'rho',linspace(0,pi/2,19)); % explicitly determine theta and rho values % restrictes grids S2G = equispacedS2Grid('points',100,'MAXTHETA',75*degree); % specify maximum theta angle

plot(equispacedS2Grid('points',100,'antipodal')) % plot the grid of nodes
