Hi all,

I have a cell named Z whose elemnts are 3-dimensional matrixs as following:

z{1,1}=ones(nsm,nr, num_class)*10;
z{1,2}=ones(nsm,nr, num_class)*15;
z{1,3}=ones(nsm,nr, num_class)*20;
z{2,1}=ones(nsm,nr, num_class)*100;
z{2,2}=ones(nsm,nr, num_class)*150;
z{2,3}=ones(nsm,nr, num_class)*200;
I want to put  together all members of Z and form a matrix named ZZ, like below:
ZZ=[10  10  10  15  15  15  20  20  20;
  10  10  10  15  15  15  20  20  20;
  10  10  10  15  15  15  20  20  20;
  10  10  10  15  15  15  20  20  20;
  100  100  100  150  150  150  200  200  200;
  100  100  100  150  150  150  200  200  200;
  100  100  100  150  150  150  200  200  200;
  100  100  100  150  150  150  200  200  200;];

How can I do it. Any help would be appreciated.

Thanks in advance.

在 MATLAB Online 中打开

nsm=4,
nr=3,
num_class=2
z{1,1}=ones(nsm,nr, num_class)*10;
z{1,2}=ones(nsm,nr, num_class)*15;
z{1,3}=ones(nsm,nr, num_class)*20;
z{2,1}=ones(nsm,nr, num_class)*100;
z{2,2}=ones(nsm,nr, num_class)*150;
z{2,3}=ones(nsm,nr, num_class)*200;
zz=cell2mat(z)
