mtlb_colordef
Matlab colordef emulation function
Description
There is no Scilab equivalent function for Matlab colordef but there
are equivalent instructions.
The function h = mtlb_colordef(color_option) or h =
mtlb_colordef(fig,color_option) is used by mfile2sci to replace
colordef(color_option) or colordef(fig,color_option) when it was
not possible to know what were the inputs while porting Matlab code to
Scilab. This function will determine the correct semantic at run time.
If you want to have a more efficient code it is possible to replace
mtlb_colordef calls:
- When called with one input parameter, if color_option is equal to
“black” or “none” mtlb_colordef(color_option) may be replaced by
fig = gcf();fig.background = -1;
- When called with one input parameter, if color_option is equal to
“white” mtlb_colordef(color_option) may be replaced by fig =
gcf();fig.background = -2;
- When called with two input parameters, if fig is a graphic handle
and color_option is equal to “black” or “none”
mtlb_colordef(color_option) may be replaced by fig.background =
-1;
- When called with two input parameters, if fig is a graphic handle
and color_option is equal to “white” mtlb_colordef(color_option)
may be replaced by fig.background = -2;
- When called with two input parameters, if fig is equal to “new”
and color_option is equal to “black” or “none”
mtlb_colordef(color_option) may be replaced by fig =
scf(max(winsid())+1);fig.background = -1;
- When called with two input parameters, if fig is equal to “new”
and color_option is equal to “white” mtlb_colordef(color_option)
may be replaced by fig = scf(max(winsid())+1);fig.background = -2;
- When called with one output parameter h, just add h = fig; after
equivalent instructions.
Caution: mtlb_colordef has not to be used for hand coded functions.
