MATLAB: How to split 14400×1 into 20 719×1 matrices

%smatrices

Hi i have a matrix that has 1 column and that column has 14400 elements what i want is to split it to each 719 elements so i end up with 19 of 719×1 matrices and the last one would be the remaining in size.

a - your vector;

n = 719;
m = numel(a);
out = reshape([a(:);nan(mod(-m,n),1)],n,[]);

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) ;
