Orthogonalize()

Orthogonalizes the specified matrix.

public void Orthogonalize()

Remarks

Orthogonalization is the process of making all rows orthogonal to each other. This means that any given row in the matrix will be orthogonal to any other given row in the matrix.

Because this method uses the modified Gram-Schmidt process, the resulting matrix tends to be numerically unstable. The numeric stability decreases according to the rows so that the first row is the most stable and the last row is the least stable.

This operation is performed on the rows of the matrix rather than the columns. If you wish for this operation to be performed on the columns, first transpose the input and than transpose the output.
