javasci.Scilab — This class provides the basic methods to execute Scilab code and scripts.
This class is static. Since the Scilab environnement is persistant, all variables will remain accessible with the Java application.
Method Summary :
public static void
Events() - Execute a Scilab event
public static boolean
HaveAGraph() -Check if there is any scilab
graphic window open (return True if it is the case).
public static boolean Exec(String
job) - Execute a job in scilab. return true if
there is no error.
Note that the given expression must be consistent by itself. Then, a serie of Exec defining a function will not work. Please consider calling it with a single string instruction or using a temporary file with the method ExecuteScilabScript.
For example: Scilab.Exec("function foo(); disp('bar'); endfunction"); will work when Scilab.Exec("function foo();"); Scilab.Exec("disp('bar');"); Scilab.Exec("endfunction;"); will not work since each statement being processed independently
public static native boolean ExistVar(String
VarName) - Detect if VarName exists in Scilab.
return true if Varname exist.
public static native int TypeVar(String
VarName) - Return Scilab type of VarName. See
type
public static native int
GetLastErrorCode() - Return last Error code. See
lasterror
public static boolean
ExecuteScilabScript(String scilabscriptfilename)
- Execute a scilab script (.sce) return true if
there is no error.
public static native boolean
Finish() - Terminate scilab (call scilab.quit ,
close a scilab object)

System.out.println("Variable "+myVar+" exists. Type: "+Scilab.TypeVar(myVar));
}
if (!Scilab.Exec("disp(plop);")) { // Error
System.err.println("Last error: "+Scilab.GetLastErrorCode()); // Error
}
Scilab.Finish();
