Subplot Scilab Vs Matlab

[fake...@invalid.domain]

In Scilab and Matlab for i = 1:16, subplot(4,4,i), plotthings end sets up an
4x4 array of subplots.

Matlab also allows for subplot(4,4,[9, 12]) or subplot(4,1,3) as a way
combining squares on the third row into a long graph. In scilab the
first command fails (in also fails for mtlb_scilab), the second command
doesn't cover the same squares, the resulting plot is not as wide.

5.1.1-alpha-1 on a mac
clf;
A = color("red");
for i=1:16, subplot(4,4,i); Matplot(A); xstring(1,1,sprintf("%d",i)); end
B = color("blue"); subplot(4,1,3); Matplot(B);

Hmmm... there doesn't seem to be a way to clf just a subplot region.

How does one divide the window into subplots like
+-+ +-+
| | | |
+-+ +-+
+-----+
| |
+-----+

subplot(2,2,1);Matplot(A);
subplot(2,2,2);Matplot(A);
subplot(2,1,2);Matplot(B);

xsetech([0.0,0.0,0.5,0.5]);Matplot(A);
xsetech([0.5,0.0,1.0,0.5]);Matplot(A);
xsetech([0.0,0.5,1.0,1.0]);Matplot(B);

both fail for different reasons.

Advice?

This don't work exactly as you want because subplot don't change
the value "arect" corresponding to the margin. By default the margin
is 1/8 for 1 (if L is the total width of the plot window the small
plots
have (L/4)*1/8 left and right margin while the "big plot" have a L*
(1/8).
So to have the same margin as the other plots you need 1/32. Try :

clf

for i=1:16, subplot(4,4,i); Matplot(A); xstring(1,1,sprintf("%d",i));
end

B = color("blue"); xsetech(wrect=[0,0.5,1,1/4],arect=1/32*[1,1,1,1]);
Matplot(B);

Nevertheless the solution don't work exactly
as expected because the larger of the vertical
tics marks are proportional to the plot width
and so the tics numbers are not positionned
as the others. Exploring the setting features
with the graphic editor don't show me a solution...

This effect has been reported as a bug in April. Some work was done
yesterday about that: See http://bugzilla.scilab.org/show_bug.cgi?id=4430
To be tested through the Master branch of Scilab, as it is a very
recent
update.

h=gca();
delete(h)
// does the job.
