ATAR Mathematics Applications 11 Matrices

12 flashcards · Mathematics · by Aedan Bailey

1. Identity Matrix

   A square matrix with ones on the diagonal and zeros elsewhere else. Multipying by this will leave the matrix un-changed

2. Matrix Addition

   The prosses of adding two matricies. Done with each number (eg. a11 + b11 = c11)

3. Matrix Subtraction

   The prosses of subracting two matricies. Done with each number (eg. a11 - b11 = c11)

4. Matrix Multiplication

   Multiply rows of the first matrix by columns of the second matrix. Example:

5. Row Matrix

   A matrix with only one row.

6. Column Matrix

   A matrix with only one column.

7. Square Matrix

   A matrix with equal rows and columns.

8. Zero Matrix

   A matrix with only zeros.

9. Matrix Scalar

   Multiplying a matrix by a whole number. Example:

10. Route Matrix

    Shows the number of conections between spesific points. Example:

11. If a matrix has 5 rows and 3 collumns it is a 5 x 3 matrix

12. This matrix has 2 rows|4 collumns and 4 collumns|2 rows.
