Hello 
 By using  reshape function , we can covert matrix to vector(row or 
col.) :
  My question is to convert vector(row /col) to martix. 
  Thanks in advance

Hi,

I think you can also use reshape.
The command reshape(x,M,N), convert a vector o matrix x to another 
matrix of dimension MxN

Example:

>> x=[1 2 3 4]

x =

     1     2     3     4

>> reshape(x,2,2)

ans =

     1     3
     2     4
Hope it helps,

Pilar

Abu,

you can use function RESHAPE to convert vector to matrix. For example, if A is a 1 x mn vector,
you can generate a m x n matrix by writing:

 B = reshape(A,m,n)

Best regards.

suppose u have a row vector
   
  V=[1 2 3 4 5 6 7 8 9];
   
  c1=V(1:3);
  c2=V(4:6);
  c3=V(7:9);
   
  cmat=vertcat(c1,c2,c3)    % vertical concatenating the rows to form 3 into 3 matrix
   
  r1=reshape(c1,3,1);
  r2=reshape(c2,3,1);
  r3=reshape(c3,3,1);
   
  rmat=horzcat(r1,r2,r3)     %horizontal concatenation of cols
