Answer 1

when you do plot something you can specify your 'something' by the legend to know which plot corresponds to which function. try following: t=0:0.1:10;

y1=2*t;

y2=4*t;

plot(t,y1,t,y2);

legend('2*t','4*t');

They are the inputs you want to display in string format

[William]

mystring = 'string1'

[Tor Fredrik Hove]

I thought string was defined to be a many characters after each other?

Numbers or letters. Are mystring built in or is it defined and you name it afterwards? Here I have made a script which only says grid I called it gridit. ANd I tried to legend(gridit) while only having one figure but it did not work

hi, so I'm plotting functions that depend on a variable 'r' that perhaps changes 10 times, hence r is a variable and its elements can be identified as r(i) How do I include code in a legend argument, such that for 10 curves that are plotted representing 10 diff values of r, the legend displays the corresponding value of r that is being represented by the legend. Thanks for any help Thanks. Sam
