MATLAB: Building a square matrix out of a vector vector matrix reform Hi everyone, im trying to build a [n X n] matrix from a [1 n*n] vector. can anybody give me a simple code? Best Answer Hossein, use reshape: A = 1:4*4; n = sqrt(length(A)); % if A is indeed an n*n vector B = reshape(A,n,n) Related SolutionsMATLAB: How to divide vector to matrix(same row and column) To remove extra elements and convert to square matrix A = rand(82580526,1) ; l = length(A) ; % GEt the nearest perfect square N = floor(sqrt(l)) ; % Reshape into required matrix iwant = reshape(A(1:N*N),N,N) ; To append zeros and convert to square matrix A = rand(82580526,1) ; l = length(A) ; % GEt the next perfect square N = ceil(sqrt(l)) ;% Append zeros A = [A ; zeros(N^2-l,1)] ; % Reshape into required matrix iwant = reshape(A,N,N) ; MATLAB: Going from 1 x n to n x n matrix repmat(A,100,1)where A is your vector.
