Plotting the values of a vector

Hi,

this is the code I wrote:

A=[1 1.1; 1.1 1]

l= [sym(2)/sym(3); sym(1)/sym(3)]

w=1

B=[1.09 1.44; 1.44 0.99]

r=linspace(0,1,100)

for r=0:0.01:1

p=w*(inv(B-(1+r)*A))*l

end

I would like to plot both values of the vector p on a graph to show the development of prices when r changes. Unfortunately, I could not find the right code yet. Does anyone have an idea?

Greetings Anna

Try this:

A=[1 1.1; 1.1 1];
l = [2; 1]/3;
B=[1.09 1.44; 1.44 0.99];
w=1;
r=linspace(0,1,100);
for k = 1:numel(r)
    p(:,k) = w*((B-(1+r(k))*A))\l;
end

figure
plot(r, p)
grid
xlabel('r')
ylabel('p(r)')

I replaced your inv call with the mldivide,\ operator, and eliminated the symbolic code, since it is not necessary.

EDIT —

Added plot figure —
