The solution is not ordinarily obtained by computing the inverse of 7, that is 7 –1 = 0.142857..., and then multiplying 7 –1 by 21. This would be more work and, if 7 –1 is represented to a finite number of digits, less accurate. Similar considerations apply to sets of linear equations with more than one unknown; MATLAB ® solves such equations without computing the inverse of the …

May 02, 2019 · 0. Commented: Walter Roberson on 2 May 2019. I'm having trouble getting started on finding a general solution to the following: du/dt=1-v and dv/dt=u-1 (a non-homogeneous linear system). Would the ode45 () function be the best way to do this? How would I go about getting rid of the imaginary numbers and putting it into the form of sine and cosine?
