Examples

1. JScript Example

/* Set and display the values of a matrix3
*/
var oMat3 = XSIMath.CreateMatrix3 (4.0, 0.0, 0.0, 0.0, 3.0, 0.0, 0.0, 0.0, 2.0);
vbArr = new VBArray( oMat3.Get2() );
array = vbArr.toArray();
var lineSize = 3;

//Display Matrix
Application.LogMessage( "The 9 matrix values" );
var mgsString = "";
for (i =0; i < lineSize; i++ )
{
   for (j = 0; j < lineSize; j++ )
       mgsString += "m" + i + "" + j + " " + array[ i*lineSize + j ] + "  ";
   Application.LogMessage ( mgsString );
   mgsString = "";
}
   
//Expected output:
//INFO : The 9 matrix values
//INFO : m00 4  m01 0  m02 0  
//INFO : m10 0  m11 3  m12 0  
//INFO : m20 0  m21 0  m22 2
