Z = zeros(5, 1)
zeros(3, 4)
A = ones(3,4)
O = ones(3)
M = magic(4)

B = rand(3, 5, 3) % random variables

A(4, 1)
A(8)
A(1:4, 3)
B(2, :)
M([2,3], 2)
C(2:5, 3)
A(3, 4) = 99

A' % transpose a matrix
P = a * inv(M)
A .* A
M .^ 3
A = [a, d] % concatenate horizontally, should have same number of rows
B = [b; c] % concatenate vertically, should have same number of columns
length(U) % maximum number of columns/rows
size(matrix33) % number of rows & columns
max(A)
[maxB, location] = max(B)
mean(R)

sin(A)
det(A)
eig(B)
[V, D] = eig(A)
eig(B, A)
[V, D, W] = eig(A, B)
norm(A*V - V*D)
norm(A*V - V*D, 1)
norm(A*V - V*D, 2)
norm(A*V - V*D, Inf)
