hello i want to put the value of a stem plot into a single variable For eg look at the stem plot code below:
stem(a(1).sd(20,1:2, 5,1), abs(a(2).sf(20,1:2, 5, 1)));
It plots two impulse at different time .But i want to send this plot or values in this plot to a single variable.So that whenever i plot this varibale this gives the same plot as the previos one .For eg:
test=[];
test(a(1).sd(irr,1:Narr, ird, isd), abs(a(2).sf(irr,1:Narr, ird, isd)));
stem(test);
But whenver I am running this code its showing the following error:
Subscript indices must either be real positive integers or logicals
please tell me how to remove this error and plot the variable.

Hey I have written this new code :
x= abs(ans.A(20,1:2, 5, 1));
y=abs(ans.delay(20,1:2, 5,1));
then I have multiplied each values so received by 1000 and rounded off but then when I am writing this
test=[];
test=(y,x);
Its saying index exceeds matrix dimensions

ans is a built in return variable. I don't think you should be using it like that.
And you can't say
text = (y,x);
that's not proper MATLAB syntax. Try changing the parentheses to brackets.
