How to install a "not found" function in MATLAB?

I am using Matlab R2010a on Windows 7 64 bit.

When I was using imfindcircles, I got the error.

>> [centers, radii] = imfindcircles(image,[100 400],'ObjectPolarity','dark')
??? Undefined function or method 'imfindcircles' for input arguments of type
'uint8'.

I referenced a helpful question and found out that I cannot find imfindcircles function.

>> which imfindcircles
'imfindcircles' not found.
>> help imfindcircles

imfindcircles not found.

Use the Help browser Search tab to search the documentation, or
type "help help" for help command options, such as help for methods.

I cannot find imfindcircles.m on my computer.

EDIT:

I checked the functions in the MATLAB Image Processing Toolbox, and found imread. 

>> which imread
C:\Program Files\MATLAB\R2010a\toolbox\matlab\imagesci\imread.m

I found some function in C:\Program Files\MATLAB\R2010a\toolbox\matlab\imagesci and C:\Program Files\MATLAB\R2010a\toolbox\images, but I don't have imfindcircles.m. Should I download imfindcircles.m somewhere and put it into an directory?

You need to have toolbox ver. 8.0 or greater to find imfindcircles. use "ver" to find the installed version for image processing toolbox

imfindcircles is part of the Image Processing toolbox. You need to have this toolbox and to have a valid license for it.

Did you check if you have any of the other functions in this toolbox?
