Yes Aabid i also think he has the problem in the interfacing part. I believe he might not be able to interface it correctly. Anyways Kumar i would suggest that when u double click on Matlab component Provide the path in the option Mentioned and then mention the m.file name seperately and do remember to mention the name followed by semicolon as it takes it as a command and then only it processes it and don’t forget to load the matlab component. I hope u are doing it acoording to these steps and i hope it should work . Else i would still suggest to please upload the .m file and .osd file, that would be helpfull to understand ur query.
