Function missing from toolbox

Hello all

I'd like to use the imsharpen function from the image processing toolbox, but when I do I get the error 'Undefined function imsharpen' ...etc. To check it's existence I typed the command

>> exist imsharpen

which returned the answer 0 (meaning does not exist).

However, I do have the image processing toolbox, as confirmed by typing the command

>> ver

Among the output was 'Image Processing Toolbox Version 8.0 (R2012a)' I also have access to other functions from this toolbox, for example typing

>> exist imadjust

returns 2 (meaning is on the path).

Can anyone help me access the function imsharpen?

Many thanks

This function was introduced in R2013a:

Excellent, many thanks.

I'll get to work finding the order number.

You need to upgrade to R2013.
