Consider the problem of calculating the area of a circle with a radius of 0.3 centimeters. A MATLAB^® program certainly is not needed to do that; you'd use your calculator instead, and punch in π * 0.3². However, if a table of circle areas is desired, for radii ranging from 0.1 centimeters to 100 centimeters in steps of 0.05 (e.g., 0.1, 0.15, 0.2, etc.), it would be very tedious to use a calculator and write it all down. ...
