ubuntu - OSError: libcublas.so.3: cannot open shared object file: No such file or directory

Question

I tried to import cudamat. Then I ran into the error:

OSError: libcublas.so.3: cannot open shared object file: No such file or directory

I tried to locate libcublas

/usr/local/MATLAB/MATLAB_Production_Server/R2013a/bin/glnxa64/libcublas.so.5.0
/usr/local/MATLAB/MATLAB_Production_Server/R2013a/bin/glnxa64/libcublas.so.5.0.40
/usr/local/cuda-5.5/lib/libcublas.so
/usr/local/cuda-5.5/lib/libcublas.so.5.5
/usr/local/cuda-5.5/lib/libcublas.so.5.5.22
/usr/local/cuda-5.5/lib/libcublas_device.a
/usr/local/cuda-5.5/lib64/libcublas.so
/usr/local/cuda-5.5/lib64/libcublas.so.5.5
/usr/local/cuda-5.5/lib64/libcublas.so.5.5.22
/usr/local/cuda-5.5/lib64/libcublas_device.a
/usr/local/cuda-5.5/targets/x86_64-linux/lib/libcublas.so
/usr/local/cuda-5.5/targets/x86_64-linux/lib/libcublas.so.5.5

/usr/local/cuda-5.5/targets/x86_64-linux/lib/libcublas_device.a

What can I do? I'm sorry I'm not familiar with ubuntu. Thank you !

QUESTION CLOSED

I solved this myself.

first set PATH and LD_LIBRARY_PATH

$ export PATH=/usr/local/cuda-5.5/bin:$PATH
$ export LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:$LD_LIBRARY_PATH

Then build a symbolic link

sudo ln -s /usr/local/cuda-5.5/lib64/libcublas.so /usr/local/cuda-5.5/lib64/libcublas.so.3
