Hi every one

i have a 3d array with dimension 51*71*3 and i want to obtain column vector 153*1

d=(51*71*3)

n=d(:,:,1) so now 51*71

r=d(:,:,2) becomes 51*71

c=data(:,3) becomes51*71

so now b=[n;r;c] 153*71

but i need153*1 instead

how can i obtain this vector

thanks in advance

x = rand(51, 71, 3);
v = reshape(x(:, 27, :), [], 1);
size(v)
ans = 1×2
   153     1

@RADWAN A F ZEYADI The random vector was just to generate sample data of the same size as your problem. Jan is not suggesting that you need to use rand( ) in your code. E.g., using your d variable:

v = reshape(d(:, 27, :), [], 1);
