J = blkdiag(rand(2,2),ones(3,2)) % 5-by-4 block diagonal matrix I = logspace(0,2,6) % 1-by-6 matrix of log-spaced numbers from 10^0 to 10^2 = meshgrid(1:5) % 5-by-5 grids of numbers A = zeros(4,5) % 4-by-5 matrix of all zerosī = ones (2,3) % 2-by-3 matrix of all onesĬ = rand(3,3) % 3-by-3 matrix of uniform random numbers in ĭ = randn(2,5) % 2-by-5 matrix of standard normally distributed numbers D = Īlternatively, there are several functions that will generate matrices for us. A = 1:10 % start at 1, increment by 1, stop at 10ī = 1:2:10 % start at 1, increment by 2, stop at 10Ĭ = 10:-1:3 % start at 10, decrement by 1, stop at 3 A = We can often exploit patterns in the entries to create matrices more succinctly. We, (and Matlab) always refer to rows first and columns second. ![]() We say that this matrix is of size 4-by-3 indicating that it has 4 rows and 3 columns. Entries on each row are separated by a space or comma and rows are separated by semicolons, (or newlines). We begin by simply entering data directly. There are a number of ways to create a matrix in Matlab.
