It's because your MATLAB installation directory is not added in your $PATH. Assuming the MATLAB installation directory is /usr/local/MATLAB/R2019b, you need to add the sub directory "bin".
If you have sudo privilege, create a symbolic link in /usr/local/bin.
sudo ln -s /usr/local/MATLAB/R2019b/bin/matlab /usr/local/bin/matlab
If you don't have sudo privilege, change your PATH environment dynamically.
export PATH=$PATH:/usr/local/MATLAB/R2019b/bin
It might be convinient to add path in your bashrc file.
vi ~/.bashrc
and add the export PATH command written above in bashrc.
Then, save the bashrc and reload.
source ~/.bashrc

If you can use sudo, you can delete symbolic link under /usr/local/bin
sudo rm /usr/local/bin/matlab
If not, you can change .bashrc file.
vi ~/.bashrc
Then delete the line in .bashrc.
export PATH=$PATH:/usr/local/MATLAB/R2019b/bin
After saving .bashrc, reflect the change by the following.
source ~/.bashrc
