MATLABmatrix manipulation

% i have a matrix 4×32 , and i need to sum the element to obtain a matrix 4×4
clear all
clc
A= randn(4,32) ;
% (1 5 9 13 17 21 25 29) i need to take this colum and sum in row ( sum,2) so i obtain a matrix 4×1
%(2 6 10 14 18 22 26 30) i need to take this colum and sum in row ( sum,2) so i obtain a matrix 4×1
%(3 7 11 15 19 23 27 31) i need to take this colum and sum in row ( sum,2) so i obtain a matrix 4×1
%(4 8 12 16 20 24 28 32) i need to take this colum and sum in row ( sum,2) so i obtain a matrix 4×1
%to obtain at the end a matrix 4×4
% thank you

  • Z=permute(reshape(A.',8,4,[]),[2,1,3]);
    Wanted = reshape(sum(Z,2),4,[])
