I'm trying to install matlab r2017b. The installation process is done without any problems but now I can't open matlab. (In installation I chose the one it says I have a license file. I entered my license key but it did not ask for license file)

```
Preparing installation files ...
Installing ...
Finished
matlab
matlab: command not found
export PATH=/usr/local/MATLAB/R2017a/bin:$PATH
alias matlab=’LD_PRELOAD=/usr/lib64/libstdc++.so.6 matlab -desktop’
bash: alias: -desktop’: not found
```

I also tried to start license manager but it failed.

```
cd /usr/local/MATLAB/R2017b/etc/
/usr/local/MATLAB/R2017b/etc$ ./lmstart
bash: ./lmstart: No such file or directory
```
