Hi Amneet,

I repeated the same procedure again and this time it is working.
*$g++ -std=c++11 -I /usr/local/MATLAB/R2020b/extern/include/ -L
/usr/local/MATLAB/R2020b/extern/bin/glnxa64/ -pthread myEngineApp2.cpp
-lMatlabDataArray -lMatlabEngine*
*$LD_LIBRARY_PATH=/usr/local/MATLAB/R2020b/extern/bin/glnxa64:/usr/local/MATLAB/R2020b/sys/os/glnxa64*
*$export LD_LIBRARY_PATH*
*$./a.out*
Square root of -2 is 0 + 1.41421i
Square root of 2 is 1.41421 + 0i
Square root of 6 is 2.44949 + 0i
Square root of 8 is 2.82843 + 0i
I don't know how it is working this time?

Thanks and regards
Srinivas
