MATLAB Quick start

Create matrix

% Direct method
a = [1, 2, 3; 4, 5, 6; 7, 8, 9];

% colon 1D matrix  (start : step size : end)  The step size is 1, which can be omitted.
b = 1:1:10;	% 1,2,...10
b = 1:10;	% Equivalent to above

% function generation
	% linspace(start, end, number of elements), Arithmetic generates a 1D matrix with the specified number of elements.
	% If the number of elements is omitted, the default is 100.
		c = linspace(0, 10, 5);

% function generation
	% special matrix
		e = eye(4);			% eye(dimension)	unit array
		z = zeros(1, 4);	% zeros(dimension)	all 0
		o = ones(4, 1);	% ones(dimension)	all 1
		r = rand(4);		% rand(dimension)	0 to 1 distributed random array
		rn = randn(4);		% randn(dimension)	0 mean, Gaussian random array
