checks which gb data are within given polygon
Syntax
ind = inpolygon(gb,[xmin,ymin,dx,dy]) % select indices by rectangle
ind = inpolygon(gb,[x1 y1; x2 y2; x3 y3; x4 y4]) % select indices by poylgon
gb = gb(ind) % select gb data by indicesInput
| gb | grainBoundary |
| xmin, xmax | lower left corner of a rectangle |
| dx, dy | extent of a rectangle |
| x, y | vertices of a polygon |
Output
| ind | logical |
