I have a system of equations with variables that are numbered (m1, m2, ... , m12). When I use "equationsToMatrix", I want to preserve this order, how do I do this?이 질문에 답변하려면 로그인하십시오.채택된 답...
Convert a system of linear equations to matrix form.equationsToMatrixautomatically detects the variables in the equations by usingsymvar. The returned coefficient matrix follows the variable order determined bysymvar. symsxyzeqns = [x+y-2*z == 0, x+y+z == 1, 2*y-z == -5]; [A,b] ...

Write the matrix equation as a system of linear equations without matrices. (3x2 matrix) (2x2 matrix) = (3x1 matrix) Solve the following matrix equation for a, b, c, and d. [a - b b + c 3 d + c 2 a - 4 d] = [8 2 7 8] Find t...
newEqs = reduceDAEToODE(eqs,vars) converts a high-index system of first-order semilinear algebraic equations eqs to an equivalent system of ordinary differential equations, newEqs. The differential index of the new system is 0, that is, the Jacobian of newEqs with respect to the derivatives...
odeFunctionreturns a function handle suitable for the ODE solvers such asode45,ode15s,ode23t, and others. The only ODE solver that does not accept this function handle is the solver for fully implicit differential equations,ode15i. To convert the system of equations to a function handle suitabl...

However if we want to be able to handle the different symbolic cases then we might want the second solution which says that there are solutions if a and b are both zero but in that case x and y can be anything. This is like the difference between factor_system and factor_system_cond:...
Transfer function numerator coefficients, returned as a vector or matrix. If the system has p inputs and q outputs and is described by n state variables, then b is q-by-(n + 1) for each input. The coefficients are returned in descending powers of s or z. a— Transfer function denomin...
