Hello Friends, I have a small problem, I am solving a first order equation problem, and i use euler, heund, range-kutta, and ode45 methods, so when I try display a table in the matlab command Window devolve me the following error:

Error using horzcat Dimensions of matrices being concatenated are not consistent.

if true
  % code
  clear all
  tic;
  h=0.1;
  format short g
  [t,ya]=euler(@funObj,0,1,h,1);
  [t,yc]=heun(@funObj,0,1,h,1);
  [t,yd]=runge4(@funObj,0,1,h,1);
  [t,zf]=ode45(@funObj,tspan,1);
  dim = length(t);
  yx=yd;
  disp('------METODO EULER, EULER MOD., HEUN , RUNGE-KUTTA,  ODE23  , ODE45  , ODE113 , SOL. EXATA------');
  disp('t(i)      ye(i)       yem(i)    yh(i)     yk(i)      y23(i)    y45(i)  y113(i)  sol. exacta');
  disp('------------------------------------------------------------------------------------------------');
  disp([t(1:dim), ya(1:dim) , yb(1:dim) , yc(1:dim) , yd(1:dim) , y23(1:dim) , y45(1:dim) , y113(1:dim) , yx(1:dim)])               
  disp('------------------------------------------------------------------------------------------------');
