how to generate bounding box coordinates from centroid location

polyin=[235.798080444336	161.207092285156
        248.257690429688	206.053085327148
        340.019195556641	180.559265136719
        327.559875488281	135.713150024414]

 [x,y] = centroid(polyin);

i want the bounding box coordinates from output [x y].

please help

The centroid alone does not carry enough information to determine the bounding box, but you can instead do

polyin=[235.798080444336	161.207092285156
        248.257690429688	206.053085327148
        340.019195556641	180.559265136719
        327.559875488281	135.713150024414];


[xlim,ylim] = boundingbox( polyshape(polyin) )

xlim = 1×2

235.7981 340.0192

ylim = 1×2

135.7132 206.0531
