matrix- a rectangular array of numbers, algebraic symbols, or mathematical functions

To determine:

  • order
  • position

Orders are determined by row X column








   ROW \begin{bmatrix} 9 & 8 & 6 \ 1 & 2 & 7 \ 4 & 9 & 2 \ 6 & 0 & 5 \end{bmatrix}


Since this has 4 rows and 3 columns it is a 4X3 matrix.



Find the location:


Find a1,2


The 1st # refers to the row...  the 2nd # refers to the column...

Go to the 1st row:

     Number sequence: 2 3 -1 6

Go to the 2nd column:

     Number sequence 3 -1 1

The row and column meet at 3.
