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