Asking User a Question with Variables

Why does this not work? How do I ask the user questions involving changing variables?

What are you having trouble with, exactly?

For some reason my copy and paste no longer works in my editor. I've checked all my shortcuts and theyre one there - but it still does not work.

Answer 1

[JESUS DAVID ARIZA ROYETH]

solution:

answer=inputdlg({'nodes'});
nodes=str2double(answer(1,1));
nodematrix=Inf(nodes);
A=0;
B=1;
while A<nodes
    B=B+1;
    A=A+1;
    answer=input(['Enter resistance between ',num2str(A),' and ',num2str(B)])
end

[Emma Sellers]

Is there a way I can do this with inputdlg? I tried and it just split my question up really strangley.

[Emma Sellers]

answer = inputdlg({'Enter resistance between ',num2str(A),' and ', num2str(B)''})

[JESUS DAVID ARIZA ROYETH]

something like this?

answer=inputdlg({'nodes'});
nodes=str2double(answer(1,1));
nodematrix=Inf(nodes);
A=0;
B=1;
answer=[];
while A<nodes
    B=B+1;
    A=A+1;
    answer(end+1)=str2double(inputdlg(['Enter resistance between ',num2str(A),' and ',num2str(B)]));
end
disp(answer)

[Emma Sellers]

Yes! Thank you!

Answer 2

[Steven Lord]

For this you could use num2str as JESUS DAVID ARIZA ROYETH posted, but I'd prefer either creating a string array to pass to the input function (if you're using a release of MATLAB that contains the string class) or using sprintf. Here's how you can use string (this requires you to use release R2017a or later to create a string using double quotes.)

A = randi([1 10]); % A scalar integer value between 1 and 10 inclusive
x = input("What positive number when squared gives " + A^2 + "? ");
if x == A
    disp("Correct!")
else
    disp("Incorrect, the correct answer is " + A + ".")
end

For sprintf:

k = 2;
s = sprintf('The value of %d*pi is approximately %f.', k, k*pi)
