This is a math solution, but I do not know how to change it to MATLAB code.
I would like you to help me.

From my understanding you want to convert the mathematical equations provided in the picture into MATLAB code. Here is the code which might help you:
ra=[0 0.3 0.12]
rb=[0 0.35 0.15]
omega=[0 1.5 2.6]
ab=[0 -2.73 1.575]
%omega x (omega x ra)
omegaCrossra = cross(omega,cross(omega,ra))
%2*omega x Vrel
vrel=cross([0 8 0],[0 0.3 0.12])
twoTimesOmegaCrossVrel = cross(2*omega,vrel)
%p x (p x ra)
p=[0 8 0]
arel = cross(p,cross(p,ra))
x=norm(p)
aa=ab+omegaCrossra+twoTimesOmegaCrossVrel+arel
%Magnitude of aA
magnitudeaa=norm(aa)
%angular acceleration
alpha=cross(omega,[0 9.5 2.6])
Please refer to cross product for more information on cross products of vectors and norm documentation for calculation of magnitude of the vector.
