18
: Opens the compilation/execution menu.
21
: Opens the diagram/file management menu.
24
: Opens the block management menu.
27

31
: This menu allows to edit diagram and palettes
35
: opens up a selection dialog where user may select a desired
36
palette among all defined palettes.
39
: opens up a dialog where user may enter and modify Scilab
40
instructions to be executed when diagram is
41
loaded (\fVEdit../Load\fR menu) or evaluated (\fVSimulate../Eval\fR
42
menu) (of course instructions are also evaluated when dialog
43
returns).These instructions may be used to define Scilab variables
44
whose names are used in the block parameters definition expressions.
47
: To move a block in main Scicos window, select first the Move
48
menu item, then click on the selected block, drag the mouse to the
49
desired block position and click again to fix the position.
52
To copy a block in main Scicos window, select first the Copy menu item,
53
then click left on the to-be-copied block (in Scicos window or in a
54
palette) , and finally click where you want the copy to be placed in
55
Scicos window. This menu item remains active until user choose an other one
58
To copy a region in main Scicos window, select first the Copy
59
menu item, then click right on a corner of the desired region (in Scicos
60
window or in a palette) , drag to select the desired region, click to

70
finally click on the to-be-replaced block. It is not possible to
71
replace a connected block with another block with different port
76
: To obtain nice diagrams, you can align ports of different blocks,
77
vertically and horizontally. select first the Align menu item, then on
78
the first port and finally on the second port. The block
79
corresponding to the second port is moved. Connected blocks cannot
84
defined block to the current palette or diagram select first this menu item, a
85
dialog box will pop up asking for the name of the GUI function
86
associated with the block. If this function is not already loaded it
87
is searched in the current directory. The user may then click at the
88
desired position of the block in the palette or diagram .
91
: This menu item is defined only in diagram edition mode. To connect an
92
output port to an input port, select first the Link menu item, then on
93
the intermediate points, if necessary, and finally on the input port.
94
Scicos tries to draw horizontal and vertical lines to form links.
96
To split a link, select first the Link menu item, then on the link
97

112
menu item, then click right on a corner of the desired region (in Scicos
113
window or in a palette), drag to select de desired region, click to
114
fix the selected region. If source diagram is a big region,
115
selection may take a while.
119
: To reverse the positions of the (regular) inputs and outputs of a
120
block placed on its sides, click on the Flip menu item first and then on
121
the selected block. This does not affect the order, nor the position
122
of the input and output event ports which are numbered from left to
123
right. A connected block cannot be flipped.
126
: Click on the Undo menu item to undo the last edit operation.
134
: In the main Scicos window, clicking on the Setup menu item invokes a
135
dialog box that allows you to change integration parameters: absolute
136
and relative error tolerances for the ode solver, the time tolerance
137
(the smallest time interval for which the ode solver is used to update
138
continuous states), and the maximum time increase realized by a single
139
call to the ode solver.
143
: This menu item need never be used since compilation is performed
144
automatically, if necessary, before the beginning of every simulation
145
(\fVRun\fR menu item).
147
Normally, a new compilation is not needed if only system parameters
148
and internal states are modified. In some cases however
149
modifications are not correctly updated and a manual compilation may
150
be needed before a Restart or a Continue. Click on this menu item to
151
compile the block diagram. Please report if you encounter such a
155
: blocks dialogs answers can be defined using Scilab
156
expressions. These expressions are
157
evaluated immediately and they are also stored as character
158
strings. Click on the Eval menu item to have them re-evaluated according
159
to the new values of underlying Scilab variables defined by context
163
: To start the simulation. If the system has already been simulated,
164
a dialog box appears where you can choose to Continue, Restart or End
165
the simulation. You may interrupt the simulation by clicking on the
166
"stop" button, change any of the block parameters and continue or
167
restart the simulation with the new values.
175
: Scicos window stores the complete history of the editing
176
session. Click on the Replot menu item to erase the history and replot
177
the diagram or palette. Replot diagram before printing or exporting

191
: Click on this menu item to change the diagram or palette's name. A
192
dialog window will pop up.
195
: Click on this menu item to save the Super Block as a new Scicos
196
block. A Scilab function is generated and saved in
197
<window_name>.sci file in the desired directory. <window_name> is the name
198
of the Super Block appearing on top of the window. A dialog allows
199
choosing the directory. This block may be added to a
200
palette using \fVEdit/AddNew\fR menu item.
203
: Saves the block diagram in the current binary file selected by a previous
204
call to \fVSaveAs\fR or \fVLoad\fR menu item. If no current binary file,
205
diagram is saved in the current directory as \fV<window_name>.cos\fR.
208
: Saves the block diagram in a binary file. A file selection dialog
212
: Save the diagram in a formatted ascii file. A dialog box
213
allows choosing the file name which must have a .cosf extension.
215
Formatted save is slower than regular save but has the advantage that
216
the generated file is system independent (usefull for exchanging data
217
on different computers.
221
Loads an ascii or binary file containing a saved block diagram.
222
A file selection dialog will pop up.
225
: select the Save as Palette menu item to save the block diagram
226
as a palette in a binary file. A dialog box allows choosing
227

select first this menu item, click next on the desired block. A dialog
269
appears that allows you to enter Scilab instructions used to draw the
270
icon. These instructions may refer to \fVorig\fR and \fVsz\fR
271
variables and more generaly to the block data structure named \fVo\fR
272
in this context (see \fVscicos_block\fR).

the pause mode (see the help on pause).
322
In the Scilab main window and you may enter Scilab instructions
323
to compute whatever you want.
324
to go back to Scicos you need to enter ""return"" or
325
"[...]=return(...)" Scilab instruction.
327
If you use "[...]=return(...)" Scilab instruction take care
328
not to modify Scicos variables such as "scs_m","scs_gc",
331
If you have modified Scicos graphic window you may restore it
