Manipulation of matrices stored as { }

let

n=[1:1:9;1:1:9];

M=n';

I used the following loop to extract parts of M to mk matrices

for k=1:3;

l=((k-1)*3)+1;

m=2+l;

mk{k}=M(l:m,1:end);

end;

In a following step I want to construct a new matrix Mnew by concatenating each mk matrix horizontally.

the wished result is:

Mnew=

1 1 4 4 7 7

2 2 5 5 8 8

3 3 6 6 9 9

To obtain Mnew I wrote:

Mnew=[mk{1,1} mk{1,2} mk{1,3}];

Question: How do I have to write to automatize the

last line above using the index k instead of

the numbers that I typed manually?

Thank you

It looks like you could use REPMAT and/or EXPAND.

Hi Matt Fig,

thank you for your suggestion.

On the other hand, I solved

the problem with

Mnew=[mk{1:3}] or

Mnew=[mk{}]

But I appreciate your attention

and intention to help.

I wish you a nice day
