A popular method for solving systems of linear equations works one of these objects into reduced "row-echelon form.
A popular method for solving systems of linear equations works one of these objects into reduced "row-echelon form." If one of these objects is (*) square, its trace is simply the sum of values along a diagonal, and these mathematical arrangements have an inverse if and only if their determinant is not zero. For ten points, name these rectangular arrays of numbers, arranged in columns and rows.
