I have a data for
days
temperature
I want to write a function that plot(x,y) that, when one inputs plot(days,temperature), that outputs
plot(days, temperature)
legend('days','temperature')
So I start with
function plottest(x,y)
plot(x,y)
end
Now how should I write
legend
?

If you want to get the variable name inside a function, you can use the "inputname" function:
function plottest(x,y)
plot(x,y)
legend(inputname(1),inputname(2))
end
However, in your plot you only have one "y" variable, so it does not make sense adding several legends. Maybe you want to change the label of the axes? In this case:
function plottest(x,y)
plot(x,y)
xlabel(inputname(1))
ylabel(inputname(2))
end
