Ran in:
this is my code
clc
clear all
syms mc m0 ms l h t dxita(t) xita(t) xita0 g n ii temp1 temp2
r0=[l/4*cosd(xita);l/4*sind(xita)];
dfr0=diff(r0,t);
ri=[0;ii*l*sind(xita)];
dfri=diff(ri,t);
j=1/12*mc*l^2;
tigz=1/2*j*dxita^2;
tigy=1/2*mc*(dfri'*dfri)
tigy(t) = 
tigy1=1/2*mc*(transpose(dfri)*dfri)
tigy1(t) = 
what's the meaning of the line on ii l ~, what's the differences of ' and transpose, are these two results the same,
thank you!

The bar over the variable means complex conjugate. ' means complex conjugate transpose, while traspose or .' means transpose without conjugating.
