Workplace: Then

The term “computer”, in use from early 17th century, meant “one who

computes”: a person performing mathematical calculations, before

electronic computers became commercially available. Teams of people

were frequently used to undertake long and often tedious calculations.

Link to user story

“One advantage of teaching with

MATLAB is that our students are

exposed to a tool that is used in

the commercial world. The quality

of the learning materials delivered

online and onsite was excellent,

enabling me to focus on teaching

analytics and working with

students.”
