MATLAB is a high - level language and interactive environment
for numerical computation, visualization, and programming.
Those expressions can, as shown by S. Chandrasekhar [53] in 1950, be computed with some additions and multiplications thanks to Gauss formulas
for the numerical computation of integrals.
Though she knew relatively little at the time about computer science, she still decided to tackle the problem herself; she taught herself how to use MATLAB, a programming language
for numerical computation, to help write the software she needed.
