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

Xold, vold, aold, xtip1,2, xorig1,2 are all 2by1 . R1 is a 2x2. Rest are scalar just a number

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', ...) ?

how do i change R1 to a single row ? the one im taking transpose of are 2x1, not scalers

alexis cordova on 31 Oct 2019

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

R1(:).' converts the 2 x 2 into 1 x 4
