Parameters:

_value - = the values of the elements of the matrix

MatrixToken

public MatrixToken(DoubleNumberToken _value)

Constructor taking a DoubleNumberToken

Parameters:

_value - = the values of the elements of the matrix

Method Detail

evaluate

public OperandToken evaluate(Token[] operands,
                             GlobalValues globals)

evaluate function - just returns the object itself

Specified by:

evaluate in class Token

Parameters:

operands - = the matrices operands (not used)

Returns:

the matrix token itself

toString

public java.lang.String toString()

Convert the matrix to a string

Specified by:

toString in class Token

Returns:

a string representation of the token

getValue

public OperandToken[][] getValue()

Return the value of the number
