matrix as desired data using for loop

suppose I had following matrix A

A(1,:)=[10 10 0.2 0 0]; A(2,:)=[10 10 10 0.3 0]; A(3,:)=[10 0.5 0 0 0];

Now I want a cell array B like this

B= [{5*5};{5*5};{5*5}];

like

 B(1)=[10 10 0.2 0 0;0 10 10 0.2 0;0 0 10 10 0.2;0.2 0 0 10 10;10 0.2 0 0 10]

similarly create

 B(2)=[[10 10 10 0.3 0;0 10 10 10 0.3;03 0 10 10 10;10 0.3 0 10 10;10 10 0.3 0 10]

and B(3) also.

thanks

In just two lines (could easily be written in one line):

>> A = [10,10,0.2,0,0;10,10,10,0.3,0;10,0.5,0,0,0];
>> fun = @(v)toeplitz(v(1,[1,end:-1:2]),v(1,:));
>> B = cellfun(fun,num2cell(A,2),'uni',0);
>> B{:}

if I had similar matrix A size of 994*24 then how it works , I can not relate its function.because here A size is 3*5. Thanks

[Stephen23]

The code I gave you does not care what size A is. Try it.

[MUKESH KUMAR]

thanks I got it and working well
