For this last week, we were assigned to run some problems through MatLab, a programming language that engineers often use. In it we solved matrices and polynomials, simple things, but I reckon that there is a lot more to learn. Although complicated to learn initially, once I hooked onto the idea, it was fairly easy to execute. I plan to learn this language more in depth to be of use in my future.

X = inv(A)*B

2)
t=0:pi/100:2*pi;
y=sin(t);
z=cos(t);
x=cos(t).^2
plot(t,y,t,z,t,x)
