include all rows matrix in []

>> size(z)

ans =

5668 73

BB=[z(:,1),z(:,2),z(:,3)....z(:,73]

i need in [] include all rows z

how can i do it?

[Paul]

Are you sure the problem is stated correctly? As written, BB will be the same as z.

Here's a small example:

z = rand(2,3)

z = 2×3

0.0201 0.5622 0.2440 0.3879 0.1390 0.2752

BB = [z(:,1),z(:,2),z(:,3)]

BB = 2×3

0.0201 0.5622 0.2440 0.3879 0.1390 0.2752

ok..i tried to transfer my problem to a wrong example..I post my main problem hoping to make me understand with few examples

Sis is a struct

>> size(Sis)

ans =

1 73

I want to add field Matrix (z)

size(z)

ans =

5668 73

[Sis.h]=deal(z)

I can synthesize it with this code

for i=1:length(Sis)

Sis(i).New=F(:,i);

end

(but i want to avoid cicle for)

Answer 1

[Walter Roberson]

zc = num2cell(z,1);   %1 --> preserve first dimension
[Sis.h] = zc{:};     %or [Sis.h] = deal(zc{:});  

Answer 2

[Paul]

One way ....

Create example data

Sis.a = 1;
Sis = repmat(Sis,73,1);
z = rand(5668,73);

The code

[Sis.z] = cell2struct(num2cell(z,1),'z',1).z;

Verify

isequal([Sis.z],z)

ans = logical
   1

[Walter Roberson]

Sis.a = 1;
Sis = repmat(Sis,73,1);
z = rand(5668,73);
[Sis.z] = struct('z', num2cell(z,1)).z;
isequal([Sis.z],z)

ans = logical
   1
