Thanks for the tutorial. It's a piece of cake for me to learn new languages if I can see a quick tutorial like this one.
I'm a long time programmer machine, assembly, Delphi, VB, C and many others programmer. I was recently laid off and finding a lot of companies are using MatLab now. Seeing your tutorials, I understand why it's become so popular.

I have two matrices of different sizes: say A(n, 2) and B(m, 2). How to find the "Union" or "Intersection" of these two matrices?

*Hope the result will be: C(k, 2)= A ⋃ B D(p, 2) =A ∩ B

**Thanks so much,

Is there a way to create a 10x1 single row as time step 0 with the array elements populated with variables defined by equations and then automatically create a new array that borrows values from the previous array?

MATLAB code to rotate an array elements in clockwise direction without using builtin function----
x=input('Enter the array:');
Y=[];
a=input('Enter the required amount of circular shift:');
k=1;
for i=a+1:length(x)
Y(k)=x(i);
k=k+1;
end
for i=1:a
Y(k)=x(i);
k=k+1;
end
disp(Y)
