This chapter extends several functional equations to the case of vector or matrix equations of vector or matrix variables. In some cases, there is a direct extension because the properties of groups can be made use of, but in others, this extension is much more complicated or becomes ...
equation x 1 a 1 +x 2 a 2 +x 3 a 3 = b. (o) The set Span{u, v} is always visualized as a plane through the origin. (p) A vector b is a linear combination of the columns of a matrix A if and only if the equation Ax = b has at least one solution. (q) The ...
Let A be a 3x4 matrix and b1,b2 be two vectors in R3 such that both matrix equations Ax=b1 and Ay=b2 are consistent.Prove that there exists a vector p?R4 such that the set of solutions y to the second equation is the set of all vectors of the form x+p,where x is any ...

("linearized"). This viewpoint makes it easy to generalize derivatives, to scalar-valued functions of vectors where f′(x) is the transposed gradient (∇f)ᵀ, to vector-valued functions of vectors where f′(x) is theJacobian matrix, and even to matrix-valued functions of matrices like...

For example, if outputForm is "vector", then the solution of the matrix equation A*X = B is X(P,:) = R\C. The default value of outputForm is "matrix" such that the solution to A*X = B is X = P*(R\C). [___] = qr(A,B,0) is equivalent to qr(A,B,"econ","...
Specify the independent variables x(t), y(t), and z(t) in the equations as a symbolic vector vars. Use the equationsToMatrix function to convert the system of equations into the matrix form. Get vars = [x(t); y(t); z(t)]; [A,b] = equationsToMatrix(eqn,vars) A = ⎛...
The previous example was helpful for presenting the dimensional analysis validation, but the equation itself only contained scalar operation. We will show here how vector, spinor, and matrix operations can be combined in a compact syntax to perform advanced calculations. In this example we reproduce...
