[Solved] Height of matrix and vector of same dimension

[ElBender]

Hi all!

I have a matrix problem that a cant sove since hours. Maybe one of you guys has a solution. That would be great!
I have matrices and vectors on the same equation. But because of small and big letters, the rows of the matrix compared to the vetor do not have the equal height.

left [
stack{dot u # dot v # dot p # dot r}
right ]
=
left [ matrix{
X_u # X_v # X_p # X_q ##
Y_u # Y_v # Y_p # Y_q ##
L_u # L_v # L_p # L_q ##
M_u # M_v # M_p # M_q
}right ]

Thank for solutions!!

Hi, and welcome to the forum. Perhaps this?

• left [
     size +3 { stack{dot u # dot v # dot p # dot r} }
  right ]
  = 
  left [ matrix{
     X_u # X_v # X_p # X_q ##
     Y_u # Y_v # Y_p # Y_q ##
     L_u # L_v # L_p # L_q ##
     M_u # M_v # M_p # M_q 
  } right ]

Maybe ...

• left [
  matrix{
    {phantom "|"_"|"} dot u {phantom "|"_"|"} ##
    {phantom "|"_"|"} dot v {phantom "|"_"|"} ##
    {phantom "|"_"|"} dot p {phantom "|"_"|"} ##
    {phantom "|"_"|"} dot r {phantom "|"_"|"}
  }
  right ]
  =
  left [
  matrix{
    X_u # X_v # X_p # X_q ##
    Y_u # Y_v # Y_p # Y_q ##
    L_u # L_v # L_p # L_q ##
    M_u # M_v # M_p # M_q
  }
  right ]

Prefect!
Both solutions work!
The "phantom" hint is very smart.
