MATLAB: Need Greek letter \epsilon_{r} in the ‘prompt’ argument of input function

Question

Hi,

I am requesting for an user input as:

EPS_R = input('\epsilon_{r} of the material = ');

and I am getting :

epsilon_{r} of the material =

but I want it to be:

of the material =

Any help will be appreciated. Thank you!

Answer 1

Use the inputdlg function instead:

opts.Interpreter = 'tex';
EPS_Rc = inputdlg('\epsilon_{r} of the material = ', ' ', [1 35], {' '}, opts);
EPS_R = str2double(EPS_Rc);

.
