in this linear matrix. q_1, q_2....the input matrix are 1*11 double. all the F2y,F3x...in the out put are 1*11 double. I want to solve the Sol for each value of input ,output

yes i know i can not put a 1*11douuble into the matrx. But is there any ways i can use the loop or something to make each value of q and each value of F into the matrix? If I manualy put each value of q and each value of F2y. I would probably need to type the matrix 121 times. I certainly just want each value of q for the corespondinbg each value of F

Could you please explain 'to make each value of q and each value of F into the matrix' and 'I certainly just want each value of q for the corespondinbg each value of F'. It might be useful to provide an example.
