Implement the class DoubleMatrix, which is a two-dimensional array of doubles. In addition to constructor methods, provide methods for matrix mutliplication and for creating an identity matrix.
The matrix multiplication method should implement C = AB, where the matrix A is an instance of DoubleMatrix and is passed in as a parameter.
When you run your program it should print the results of the two following matrix multiplications. In both cases, the A matrix is the first one.
[[ 4 ]
[[2 4 -2 3] [ 1 ]
[-1 0 2 3]] [-1 ]
[ 3 ]]
[[2 3 -1] [[1]
[1 0 1] [2]
[4 -3 1] [3]]
Feel free to use the programming language of your choice. It needn't be object-oriented. For Java programmers, email your code as a single file to the TA, Selim Yargici (yargicis@gusun), by the start of class on the due date with a subject line of "project1.java". For everyone else, hand in a disk with your source and executable by the start of class on the due date.
