I want to lebel the 6 solution on the curves of my plot but idont know how to: here is my matlab script below:

clear all

close all

func =@(i,j) y(j)^2 - log(y(j))^2 - 4*log(x(i)) - 4*(1/x(i)) - 3;

x = 0.7:0.05:1.5;

y = 0.7:0.05:1.5;

for i = 1:length(x)

for j = 1:length(y)

c(i,j) = y(j)^2 - 2*log(y(j)) - 4*log(x(i)) - 4*(1/x(i));

end

end

contour(x,y,c);xlabel('r/r_c');ylabel('(v/c_s)^2');

xlabel('r/r_c');ylabel('(v/c_s)^2');

colorbar;colormap('parula');

xticks(1:round(length(x)/10):length(x));

xticklabels(x(1:floor(length(x)/10):end));

yticks(1:round(length(y)/10):length(y));

yticklabels(y(1:floor(length(y)/10):end));

Where are points you want to mark?

Like tge above photo basically

[darova]

You mean text function?
