I have a vector A = [10 40 60 80]
and a vecor B = [5 6 7 8]
I need to create a plot where the x-axis is B and the y-axis is A in the logarithmic scale. Then I need to find the intersection of the fitting line of the scatter with the y-axis.
I used semilogy(B,A) but that only gives me the line and I need to find the intersection.
