Interface MatrixEBETransformation

public interface MatrixEBETransformation

MatrixEBETransformation

Encapsulates an operation that can be performed on each element of a matrix

Meant for scalar ebe transformations or ebe function application.

Examples: As annonymous classes ..

 private static Matrix scalarAddition(Matrix m, final double s) {
       return MatrixEBETransformer.ebeTransform(m, new MatrixEBETransformation() {
           public double transform(double element) {
               return element + s; //could be +, *, -, /
           }
       });
   }
 

 // unary minus or negation
 new MatrixEBETransformation() {
      double transform(double element) {
          return -element;
      }
 };
 

 //scalar multiplication
 new MatrixEBETransformation() {
      double transform(double element) {
          return 2 * element;
      }
 };
 

 // function application
 new MatrixEBETransformation() {
      double transform(double element) {
          return Math.sin(element);
      }
 };
 

This interface may be dropped in the future in favour of the conditional one as that one essentially allows for everything that this interface allows .. or we might drop the MatrixConditionalEBETransformation, replacing the method here with the one in MatrixConditionalEBETransformation
