disp_lut — 查找表（lut）的图形视图。
disp_lut 已过时，仅出于向后兼容性考虑而保留。
disp_lut( : : WindowHandle, Row, Column, Scale : )
disp_lut displays a graphical view of the look-up-table (lut)
in the valid window. A look-up-table defines the transformation of
image gray values to colors/gray levels on the screen. On most systems
this can be modified.
disp_lut creates a graphical view of the table assigned to
the output window with the logical window number WindowHandle and
displays it for every basic color
(red, green, blue).
Row 和 Column define the position of the center of
the graphic.
Scale allows scaling of the graphic, whereby 1 means
displaying all 256 values, 2 means displaying 128 values, 3
means displaying only 64 values, etc.
Tables for monochrome-representations are displayed in the currently set
color (see set_color, set_rgb, etc.).
Tables for displaying “false colors” are viewed with red, green and blue
for each color component.
