hi,i am getting error as not enough input arguments,while i run the below code....?? please let me know that?(the error is in second line of code)

function [x]=trio(m,n)
  x=rand([3*m n]);
  x(1:3*m/3,:)=1;
  x(3*m/3+1:3*m/3+m,:)=2;
  x(3*m/3+m+1:end,:)=3;
end

Works fine here. Show us how you called it.

NB: 3*m/3 --> m so the above could be more succinctly written as

function [x]=trio(m,n)
  x=rand([3*m n]);
  x(1:m,:)=1;
  x(m+1:2*m,:)=2;
  x(2*m+1:end,:)=3;
end

Works fine for me, if called with 2 input arguments:

res = trio(3,4)

function x=trio(m,n)
    x=rand([3*m n]);
    x(1:3*m/3,:)=1;
    x(3*m/3+1:3*m/3+m,:)=2;
    x(3*m/3+m+1:end,:)=3;
end
