The corresponding function is called with the remaining inputs. (ii) If last input is numeric and not a scalar: \matlab+imshow+ is called with all inputs. (iii) If last input is char: \matlab+imwrite+ is called with all inputs. (i, iii) For \matlab+imwrite+, the first input of type char is interpreted as file name. If it has no extension '.png' is added; if it's empty it is replaced by 'image.png'; and if non existent 'image.png' is used as final input. (i, ii, iii) For \matl+imshow+ and \matl+imwrite+, if the second input is numeric, has the shape of a colormap, and has some entry greater than $1$, it is normalized by converting to \matlab+uint8+, then to \matlab+double+, and then dividing by $255$. For \matlab+imagesc+ and \matlab+image+, the function call is followed by \matlab+axis ij, axis image+. For \matlab+imagesc+, \matlab+image+ and \matlab+imshow+, \matlab+drawnow+ is called to update figure immediately
