how can i display b(i,j) matrix.i have attached the code i am working with.

clear all; a=[1,2,3,4;4,3,2,3]; for i=1,size(a,1) for j=1,size(a,2) b(i,j)=a(i,j) disp(b) // this is not giving the out i need end end

     a=[1,2,3,4;4,3,2,3]; 
     [m,n]=size(a)
     b = zeros(m,n) % pre-allocate for speed 
     for i=1:m % not , should be :
         for j=1:n
             b(i,j)=a(i,j);
    %          disp(b) % this is not giving the out i need e
         end
     end

             disp(b)

it doesnot shows complete matrix

[madhan ravi]

what's your desired output matrix b size? but with th above Coe you can directly copy the matrix from a i.e..

b = a;

I don't see the reason for you to use loop here

[madhan ravi]

if something is not clear let know

Try double clicking b in the workspace panel to bring it up in the variable editor. Or you can put the cursor next to b and type control-d to bring it up in the variable editor.
