I'm attempting to use the imsegkmeans function. I have the Image Processing toolbox installed, yet MATLAB displays the following:

--------------------------------------------------------------------------------

Undefined function or variable 'imsegkmeans'.

Error in Kmeans (line 17)

pixel_labels = imsegkmeans(ab,nColors,'NumAttempts',5);

--------------------------------------------------------------------------------

Thanks in advance

Not true. It will automatically be on the path for the Image Processing Toolbox if you have that toolbox. Since it will be on the search path, you DO NOT need to include it in the current folder.

Most likely you don't have a recent enough version, like the staff Answer below says.

I think you might be getting this error because you are trying to use it on version earlier than MATLAB R2018b.This feature was introduced in R2018b .You can take a look at release notes to check new functionalities introduced in an Update : Release Notes.

To do k-means clustering in an earlier version , you can follow the workflow mentioned in the link below :https://in.mathworks.com/help/images/color-based-segmentation-using-k-means-clustering.html
