Hello,

I have the following question:

this is my code:

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 k = 1:numel(r)

p(:,k)=(inv(B-(1+r(k))*A))*l

end

The p vector consists out of p1 and p2. After the loop is finished I would like to calculate p1/p2 (also in a loop as I would like to plot p1/p2 against r). Unfortunately, I could not find any references to this case.

Does anyone have a solution for dividing the values of a vector.

Greetings,

Anna

q can be calculated as follows

q = p(1,:) ./ p(2,:)

or

q(:,k) = p(1,k) / p(2,k)

Then, you can plot q against r.

Try this:

A=[1 1.1; 1.1 1];

l = [2; 1]/3; % Create As Column Vector

w=1;

B=[1.09 1.44; 1.44 0.99];

r=linspace(0,1,100);

for k = 1:numel(r)

p(:,k)=(B-(1+r(k))*A)\l; % Replace ‘inv’ Call With ‘\’

end

p_div = p(1,:)./p(2,:);

figure

plot(r, p_div)

grid

xlabel('$r$', 'Interpreter','latex')

ylabel('$\frac{p_1}{p_2}$', 'Interpreter','latex')
