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

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

I tried that and it still doesn't work.

Okay now use
which -all input
and tell us what you get back.

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.

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

perfect... So rename the first file, to say 'troublesome.m'. Shadow effect will go. then run 'troublesome.m'
Hopefully your troubles will be gone.

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.

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