[Scilab-users] scilab ode from java

[P J Binu]

Hi,

I am trying to call ode from java. but it shows 

an error like following, 

foo[1,1] = sci_matrix

getHeight() = 1

getHeight() = 5

intdy-- t (=r1) illegal 

where r1 is : 0.2500000000000D-01 

t n est pas entre tcur - hu (= r1) et tcur (=r2)

where r1 is : 0.8694709664001D-02 and r2 : -0.7179037253078D-01 

lsoda-- problems due to intdy. itask=i1,tout=r1

where i1 is : 1 

where r1 is : 0.2500000000000D-01 

testing 

 

my code is as follows,

 

class Example1 {

public static void main(String[] args) throws Exception{

try {

Scilab sci = new Scilab(true);

if (sci.open())

{

sci.exec("function dx=f(t,x);dx =sin(2*t);endfunction");

ScilabDouble t0=new ScilabDouble(0);

ScilabDouble x0=new ScilabDouble(0.5);

sci.put("t0",t0);

sci.put("x0",x0);

sci.exec("[t] = linspace(0,0.1,5);");

ScilabType t=sci.get("t"); 

System.out.println("foo[1,1] = " + t.getType());

System.out.println("getHeight() = " + t.getHeight());

System.out.println("getWidth() = " + t.getWidth()); 

sci.put("t",t);

sci.exec("x = ode ( t0 , x0 , t , f ) ;");

sci.exec("plot2d(t,x);"); 

System.out.println("testing " );

}

else 

System.out.println("Not opening scilab " );

} catch (org.scilab.modules.javasci.JavasciException e) {

System.out.println("test " );

System.err.println("An exception occurred: " + e.getMessage());

}

}

}
