Hello, I am trying hard to get code running, however I am stuck at a place. Please help me.
I have declared 3 symbolic variables x1,x2,x3. gr is a column vector and function of x1,x2,x3. p1 is a column vector of constants. I want to substitute values of x2,x2,x3 by first, second, and row of p1. That is x1 = 957/2500, x2=-293/1250, etc. And I want to make it as a new vector gr2. MATLAB is giving errors of inconsistent dimensions. Please help! Thanks
syms x1 x2 x3gr = 2*x1 + 2*x2 2*x1 + 4*x2 + 2*x3 2*x2 + 4*x3p1 = 957/2500 -293/1250 371/5000gr2=subs(gr,[x1,x2,x3],[p1(1),p1(2),p1(3)]);
