The same terminology is used for the associated quadratic forms. It is worth recalling that any matrix is singular if and only if it has 0 as an eigenvalue. This is because the determinant of a matrix is the product of its eigenvalues. Symmetric Matrices and MATLAB. MATLAB has a function called eig that returns the eigenvalues of a matrix.

The default type for any variable or quantity in MATLAB is a matrix---a two-dimensional array. Scalars and vectors are regarded as special cases of matrices. A scalar is a 1 by 1matrix, while a vector is an n by 1 or 1 by n matrix. A matrix is entered by rows, with entries in a row separated by spaces or commas, and the rows separated by ...

Matrix operations. rref(A) calculates the reduced row echelon form of the matrix A. rrefmovie(A) shows the major steps in calculating the reduced row echelon form of a matrix. A*v2 is the product of the matrix A and vector v2. A*B is the matrix product of matrices A and B. A\B is inv(A)*B, where inv(A) indicates the inverse of A. A/B is A*inv(B)

The left-hand matrix row you work with is the same as the row of the product matrix element you wish to calculate, The right-hand matrix column you work with is the same as the column of the product matrix element you wish to calculate. Example. Calculate the product of (in this case) two 3×3 matrices, A and B: To calculate the value of ,

The core of Matlab is a large number of powerful matrix functions that usually can be invoked with one command. For problems that cannot be directly solved with these built functions, the ability to write programs is provided. ... A*v2 is the product of the matrix A and vector v2. A*B is the matrix product of matrices A and B. A\B is inv(A)*B ...

If is an matrix and no entry of has absolute value greater than , then. In order to say anything about the 2-norm of a matrix whose entries are bounded, we need to establish some relations among the various norms we have defined. Proposition 6a.3 summarizes these, and provides the missing bound on the 2-norm of a matrix whose entries are bounded.

32 Notice that MATLAB does not distinguish between a 1x1 matrix (which is what vTw really is) and its single entry. Neither do we ordinarily, but we should remember that the product of a scalar with a matrix is not in general an instance of matrix multiplication. Notice also that the dot product is symmetric as regards v and w.

These direct MATLAB to evaluate the product and exponential separately in each position of the array, rather than to attempt matrix multiplication or expontiation, which would be undefined in this context and produce an error message.
