i have Rr=3*3 matrices and PQRg=3*110 and i want to multiply them and get AnVel=[Rr]*[PQRg]which is 3*110 ? how is possible?

You are overwriting all of AnVel every iteration of the "for" loop. It seems unlikely that is what you want to do.

Um, read the getting started tutorials?
AnVel = Rr*PQRg;
It is legal to read the documentation. You might even learn how to use the language.

YOu can happily multiply them using *.
Rr = rand(3,3) ;
PQRg = rand(3,110) ;
P = Rr*PQRg
Remmember multiplication law?
