I want to assign values from a 1d array to 2d array. How should I do it?

Please copy paste above address if image is not visible.

The function tridiagonal(n) gives values of x in a 1 dimensional array. I want to assign it to 2 dimensional array of w(s,t). However it shows error saying "Undefined function 'x' for input arguments of type 'double'."

You have not assigned a value to x. Maybe you meant:

 for s=2:m
  x = tridiagonal(n); % assign x!
  for t=1:n   
    w(s,t)=x(t);  
  end   
 end

But you can save one of the for loops:

 for s=2:m
   x = tridiagonal(n); % assign x!
   w(s, :) = x; % or x', depending on dimension of x 
 end

Thanks a lot Jan...!!! It worked...

x is not defined in your code
