 [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
