These are my inputs how can i use str2num in title so that i can display the values of inputs?

A=input('amplitude= ')                        
N=input('period=    ')

I get the following errors ??? Error using ==> title at 29 Incorrect number of input arguments

Error in ==> title at 23 h = title(gca,varargin{:});

how can i solve the issue?

I don't see how your two lines of codes are related to your question

A=input('amplitude= ')                        
N=input('period=    ')   

title(sprintf('Amplitude = %f mm, Period = %f s', A, N))

Answer 2

It is more much robust to use the 's' option for input, which can be used like this:

A = str2double(input('amplitude= ','s'));                      
N = str2double(input('period=    ','s'));
title(sprintf('Amplitude = %g mm, Period = %g s', A, N))

This avoids the possibility of arbitrary code being input and executed, which is what input without the 's' option will do.
