Is the lib file "libcublas" in your path? Have you told the complier (mex) where to find the file?

Usually you need to supply mex with something like '-L:C\MyLibs' -llibcublas

Assuming the lib file is in the folder C:\MyLibs

sir please explain your answer.... I found this way to excess cublas from net... loadlibrary('libcublas','C:\Program Files\Matlab\R2014a\extern\include\cublas.h')

No, you don't do that, you just link libraries to your code using -l parameters to mex. But you shouldn't need to link to cublas, that is linked by default for GPU MEX functions.
