Question

In what ways are matrices used in the real world?

In: Mathematics

Answer 1

Structural engineers use matrices all the time. In first year statics we’d have to solve 6 equation, 6 variable systems for 3D problems. You’d have equations for strain in all 3 dimensions, and displacement in all 3 dimensions. That gives you a 6×6 matrix which you’d then have to reduce in order to solve the equations.
