Input doesn't work

I was working on writing a script but when I included the input function I received the following error: Attempt to execute SCRIPT input as a function: /Users/Jzhang/Documents/MATLAB/input.m Error in circle_area (line 2) radius=input('Enter the radius:'); I've tried the input function in other scripts as well and they were working before but not anymore. Can anyone help me figure out this problem? Thanks

Don't call it input.m. input is the name of a built-in function. Call it something else, like myInput().

I understand that input.m is a name of a built-in-function. For this example I wanted the user to input a number for the radius, so i wrote radius=input('Please enter the radius:'). However that didn't work

[Image Analyst]

Rename /Users/Jzhang/Documents/MATLAB/input.m to /Users/Jzhang/Documents/MATLAB/myinput.m or something like that.

[Jerry]

I tried that and it still doesn't work.

Okay now use

which -all input

and tell us what you get back.

[Jerry]

so instead of radius=input('.....') use radius=which -all input('....') ?

no .. on the MATLAB command window, type

which -all input

it will show all the files with name input in your matlab path.

[Jerry]

oh i see, i got the following: >> which -all input /Users/Jzhang/Documents/MATLAB/input.m built-in (/Applications/MATLAB_R2013b.app/toolbox/matlab/lang/input) % Shadowed

[ES]

perfect... So rename the first file, to say 'troublesome.m'. Shadow effect will go. then run 'troublesome.m'

Hopefully your troubles will be gone.

[Walter Roberson]

That would not have happened if you had done the renaming that Image Analyst suggested. Though you might have needed to use the command

clear input

after you did the rename.

[Jerry]

I'm sorry I'm a beginner at matlab. So rename input.m to troublesome.m?

[Jerry]

nevermind, i got it. Thanks!
