MATLAB: Error using str = input(prompt,’s’)

Question

I need to ask user whether they have control data or not. if the answer was yes, I need to do other steps.

I tried this coammand:

prompt2='Do you have control? answer Yes/No ';
YesNo = input(prompt2,s); 
if YesNo=='Yes'
end

and I got this error:

Undefined function or variable 's'.

What is wrong with this code?

Answer 1

YesNo = input(prompt2,'s')
