I have the following string:
Now I want to use this string to produce a legend to my figure. So I use
and get this:
But I would like to have this,
which I got by using the following command:
Tthis is exactly the string Legend copied into the function legend().
How can I use directly the string Legend, without copying it to the function legend()?
Edit: I forgot the following code sniplet:
p=zeros(2*length(HG),1);
hold on;
for iter2 = 1:length(HG)
p(2*iter2-1)=plot(freq,real(n(:,iter2)), 'color', cc(iter2,:));
p(2*iter2)= plot(freq,imag(n(:,iter2)),'--', 'color', cc(iter2,:));
end
I use the variable p to skip all dotted lines in the legend.

Although Walter's comment already shows the problems with eval(), in case you still want to use the current method, then the closest you can get is something like this
fig = figure()
hold on
p(1) = plot(rand(1,10))
p(2) = plot(rand(1,10))
Legend_str1 = "[p(1) p(2)]";
Legend_str2 = "{'ABC', 'DEF'}";
legend(eval(Legend_str1), eval(Legend_str2))

You could use
Legend = ['HS+HG = 0.5+5' ;'HS+HG = 1+5'];
legend(Legend)
But make sure there are the same number of characters (including spaces) in both strings.

Following alternatives does not require that character arrays have equal lengths.
Legend = {'HS+HG=0.5+5';'HS+HG=1+5'};
legend(Legend)
or
Legend = ["HS+HG=0.5+5";"HS+HG=1+5"];
legend(Legend)
