matlab num2str error?

Hey guys I am having help with this matlab assignment. It should be easy but idk what is going on. The problem states, prompt the user to enter his or her age. Then use the disp function to report the age back to the command window. If, for example the user enters 5 when prompted for her age, your display should read: your age is 5 …….This output requires combining both character data and numerica data in the disp function, which can be accomplished by using the num2str function.

This is what I have done:
%
age = input(‘How old are you, son? ‘)
disp(‘your age is’, num2str(age))
%

and this is the error message:
How old are you, son? 6

age =

6

??? Error using ==> disp
Too many input arguments.

Error in ==> age76 at 2
disp(‘your age is’, num2str(age))

Can you guys help me out please?

Try this:

age = input(‘How old are you, son? ‘,’s');
disp(['your age is ' num2str(age)])

‘age’ is supposed to be a string, so use the ‘s’ at the end of ‘input’.
‘disp’ then should take a vector within [ ]

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. An error message is information displayed when an unexpected condition occurs, usually on a computer or other device. On modern operating systems with graphical user interfaces, error messages are often displayed using dialog boxes. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings (such as warning a computer user that they are almost out of hard disk space). Error messages are seen widely throughout computing, and are part of every operating system or computer hardware device. Proper design of error messages is an important topic in usability and other fields of humancomputer interaction.

A Practical Guide to Error-Control Coding Using MATLAB by Jing, Yuan Edition ILL, 0


$50.49


This practical resource provides engineers with a comprehensive understanding of error control coding, an essential and widely applied area in modern digital communications. The goal of error control coding is to encode information in such a way that even if the channel (or storage medium) introduces errors, the receiver can correct the errors and recover the original transmitted information. This book includes the most useful modern and classic codes, including block, Reed Solomon, convolutional, turbo, and LDPC codes. Professionals find clear guidance on code construction, decoding algorithms, and error correcting performances. Moreover, this unique book introduces computer simulations integrally to help readers master key concepts. Including a companion DVD with MATLAB programs and supported with over 540 equations, this hands-on reference provides an in-depth treatment of a wide range of practical implementation issues. DVD Included! Contains carefully designed MATLAB programs that practitioners can apply to their projects in the field.

Runtime Error 200


Runtime Error 200

High Quality Content by WIKIPEDIA articles Runtime error 200 is the standard error message by Borlands Pascal compilers, standing for Division by zero. Many older computer programs for the MSDOS operating system fail immediately on loading with this error message. In many case they were compiled with an older version of the Borland or Turbo Pascal compiler, which often generated programs which failed if executed on computers with processors faster than about 200 MHz.Borland and Turbo Pascals standard libraries included a procedure called delay(n), code created for halting the execution of the program for a given number of milliseconds. Due to the initializing of the CRT unit, this procedure is called even if the software itself doesnt do it explicitly. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.
