How to use a function which is not existing in matlab?

Hey, while doing some code for image segmentation i got stuck at an error saying "Undefined function or variable 'superpixels'". And i checked whether the function name exists on matlab search path and i found that superpixels doesnot exist. Now what should i do to use the function superpixels in matlab version R2015a.

This function is introduced in 2016a. Either use the version which has this function or write your code for the functionality.

superpixels() was introduced in R2016a, so you can upgrade, or you can write your own version of the code. Or perhaps it happens that https://www.mathworks.com/matlabcentral/fileexchange/50184-slic-superpixels-for-e%EF%AC%83cient-graph-based-dimensionality-reduction-of-hyperspectral-imagery would be useful for you.
