Albert Danial is an aerospace engineer with 35 years of experience, currently working for Northrop Grumman near Los Angeles. He has been using MATLAB since 1990 and Python since 2006. MATLAB brings endless challenges to his coworkers and himself --insufficient licenses, no licenses for toolboxes our subcontractors use, difficulty integrating MATLAB tools with other parts of our analytical infrastructure. Python eases many of our MATLAB-related headaches (not so much via MATLAB-Python integration, but rather wholesale replacement of MATLAB code with Python equivalents).
