GetCol() public method

Get one column from this matrix as a column matrix.

public GetCol ( int col ) : Matrix
col	int	The desired column.
return	Matrix

Example #1

        public void GetCol()
        {
            double[][] matrixData1 =
            {
                new[] { 1.0, 2.0 },
                new[] { 3.0, 4.0 }
            };
            double[][] matrixData2 =
            {
                new[] { 2.0 },
                new[] { 4.0 }
            };

            var matrix1 = new Matrix(matrixData1);
            var matrix2 = new Matrix(matrixData2);

            Matrix matrixCol = matrix1.GetCol(1);

            Assert.IsTrue(matrixCol.Equals(matrix2));

            try
            {
                matrix1.GetCol(3);
                Assert.IsTrue(false);
            }
            catch (MatrixError)
            {
                Assert.IsTrue(true);
            }
