Creating user defined variables and solving systems with a script

29 views (last 30 days)
Hi all, been a while since I needed a question answered, so here goes:
I am creating a script that is used to solve a system of equations defined by a user. The general form of the equation to be solved is K*u=P, where u and P are both column vectors that contain variables, and K is a square matrix the size of the number of rows in u and P. An example would be:
Where K is generated via user input, and the user is to define all values of u and P. My problem is that I don't know how to have matlab accept variables as a user input, and I don't know how I would solve such a system of equations using Matlab.

Use input:
K=input(' Enter matrix :\n');
% You enter the K(i,j) as :[4 5 8 7;2 3 6 5] then K is the entered matrix
