how to convert collumn matrix (nxn) into another matrix of (mxn) type .

I am working on my project where audio encryption is needed .I am stuck in a problem of converting column matrix into (mxn) type matrix. please help me its urgent

What do you mean by "column matrix(nxn)"..?

Column matrix is supposed to have only one column, so it should rather be (nx1).

I mean to say column vector of (nxn) form

Difficult to answer with that little detail.. Maybe:

 M = reshape( v, n, n ) ;

or

 M = reshape( v, n, [] ) ;

with a transposition ( .' ) afterwards if needed.

During the usage of RESHAPE function i have to mention that how many rows and column matrix we need.But in my case we have to assume n number of column vector which we have to transform in (mxn) . if i use reshape function then it looks like:-

   a=audiorecorder(8000,8,1);
   disp('start recording');
   recordblocking(a,5)
   disp('stop recording');
   play(a);
   b=getaudiodata(a);
   double (s);
   s= reshape (double(b), m, n);

here in our case we want m and n value by some logic rather look at the column vector value. Suggest me some logic and thanks for your previous suggestion.

I just don't understand what you want to achieve. After you stop recording, variable b is a 40000x1 vector. What do you want to do with it and why? Why a matrix?
