Package org.lsmp.djep.vectorJep.function Description

Functions and operators for working with vectors and matricies.

In the VectorJep package vectors are handled if a different fashion to standard Jep. The VList function converts a list of values [1,2,3] into one of the MatrixValueI types: Scaler, MVector, Matrix or Tensor.

Functions which work with Vectors in this package should handle the above types.

Furthermore if the MatrixJep package is going to be used, then classes should implement one of the interfaces either UnaryOperatorI BinaryOperatorI or NaryOperatorI interfaces. These use a more efficient method for evaluation through the calcValue methods, where an object to hold the results is provided.
