MATLAB: Undefined function ‘grayto16’ error matlab – java

image processingImage Processing ToolboxjavaMATLAB CompilerMATLAB Compiler SDKmcr

Hi, I have deployed a list of .m files in matlab to generate a Java class/package. I have imported the generated jar file and matlab JA Builder jar files into a Java project. When I run the java code which calls .m files I am getting the following error:
… Matlab M-code Stack Trace …
file C:\MCRCache\mcrCache8.1\packag0\toolbox\images\images\im2uint16.m, name im2uint16, line 62. com.mathworks.toolbox.javabuilder.MWException: Undefined function 'grayto16' for input arguments of type 'double'
grayto16 is not a .m file to include in the jar file. Ideas or suggestions please… thank you!

Just define your own then
function out=grayto16(in)
out=uint16(in);
