For a linear system A*x = B where A and B are known
Yv = [-Y 0 0; 0 Y 0; 0 0 Y];A = [5 -4 4; -5 4 3; 5 3 1];AY = A + Y; % ALSO TRIED USING: Instead of AY Y= [(5-Y) -4 4; -5 (4+Y) 3; 5 3 (Y+1)]
B = [1; 4; -2;];inverseA = inv(AY);x = inverseA*B; %vector x must satisfy
for n = 1:size(B) xr = x(n); % resultxt = 'Value %2.0f of vector x is %6.3f \n' ;
% fprintf(resultxt, n, xr)
a = x(1); b = x(2); c = x(3);
This returns me x1 x2 and x3 for the matrix in forms of a b and c respectively. I am trying to plot the values of x1 for
Y = linspace (1,12)
which does not work given that the (vector) sizes don't match. Any ideas? Thanks
