We have no information about the size of x, xold,vold, aold, xtip1, xorig1, xtip2, xorig2, U, T, Us, Up, E, or R1 .

When you are concatenating horizontally, the number of rows must be consistent. According to your comment, all variables are 1x1, but R1 is 2x2. Thus R1 is causing the error. Either change R1 to a single row, or put the variables into a cell array, which will allow for the different variable sizes.
Why are you taking the tranpose of scalers (xold', vold', ...) ?

so my 2x1 are xold, vold, aold, xtip 1 , xtip 2 , xorig1, xorig 2, are 2 x1,
R1 is a 2x2
and the rest are scalars
