Example text

Same is true for columns. An array with m rows and n columns is called an m x n array and it has a total of m n entries. An element of the array is recognized by its location-its row number and column number. These row and column identifiers are called indices of t he maLrix. Thus A( i, j) refers to a specific element of matrix A located in the ith row and jth column . These locations are unique. In MATLAB , you can also use a list of numbers for the row and column indices to access more than one element of the matrix at a time.

Here of A . x is the transpose of the tirst row 1 2 3 >> X I *X Matrix o r vector products are well­ define d be tw een c ompatibl e pairs. A ans ( x ) times a column vector ( x) of the same length gives the inner row vector 14 ' product, which i s a scalar, but a column >> vector times a row vector of the same x*x ' length gives the outer product, which is ans a matrix. 1 2 3 >> 2 4 6 3 6 9 A*x ans Look how easy it is to multiply a vector w ith a matrix, compared with = 14 Fortran or Pascal. 32 50 » A" 2 You can even e xp onenti ate 30 66 102 >> 36 42 126 150 81 A *A .

How to access an element , a row, a column, or a submatrix of a matrix. • How to multiply a matrix with a vector. • How to distinguish between array operation and matrix operation. Method: We will take a simp le 3 x 3 matrix and use its row and columns indices to manip ul at e the matrix, extract a vector, compute inner and outer product of vectors, multiply the matrix with a vector, exponentiate the matrix, and exponen­ tiat i ng each element of the matrix using an arra y operation. Commen ts: Arrays are the backbone of MATLAB computation.
