The primary functions and operators that you can use with decomposition objects are related to solving linear systems of equations. If the decomposition type is 'qr', then you cannot solve A'\B or B/A. Instead, use 'cod' for problems with those forms. ctranspose Complex conjugate transpose ...

One of the primary uses of matrix multiplication is formulating a system of equations as a matrix problem. The system of m linear equations in n unknowns a11x1+a12x2+···+a1nxn=b1a21x1+a22x2+···+a2nxn=b2⋮am1x1+am2x2+···+amnxn=bm is equivalent to a single-matrix equ...
Generalizing to matrix equations, we call an equationf(X) = Elinear iffis linear in the unknown matrixX. In this sense, the classical Sylvester equationsAX + XB = Ewithf(X) = AX+XBorA^TXA + B^TXB = Ewithg(X) = A^TXA + B^TXBare linear matrix equations in the unknown matrixX...
Equations We can express the 3×3 rotation matrix in terms of a 3×3 matrix representing the axis (The 'tilde' matrix is explained here): [R] = [I] + s*[~axis] + t*[~axis]2 or equivalently: [R] = c*[I] + s*[~axis] + t*([~axis]2 + [I]) which can be expanded...
Solving a system of linear equations using the inverse of a matrix requires the definition of two new matrices: XX is the matrix representing the variables of the system, and BB is the matrix representing the constants. Using matrix multiplication, we may define a sy...
Input or output matrices can be saved to clipboard and pasted into other input screens in the app, text files and spreadsheets. Matrix and Linear Equations entries can be saved into table and are available after application is closed and re opened. ...
