A = pi*(0.01)^2;
p = 1/(A*0.4);
mass_shaft = 1;
w = (1E5*2*pi)/60;
rad_shaft = 0.01;
E_s = 2E11;
I_S = pi*(rad_shaft^4)/4;
length_shaft = 0.4;
f = 'cos(x)*cosh(x)-1'; %function
r = [fzero(f,4.0) fzero(f,7.0) fzero(f,10.0) fzero(f,14.0)]; %roots
beta = r./length_shaft;
syms y
double Q
double B
double C_n
Q = (cos(y.*beta) + cosh(y.*beta) - ((cos(length_shaft.*beta) - ...
cosh(length_shaft.*beta))./(sin(length_shaft.*beta) - ...
sinh(beta.*length_shaft))).*(sin(y.*beta) + sinh(y.*beta))).^2;
B = int(Q,y,0,length_shaft);
C_n = (B.*A*p).^(-0.5);
This is my code and whenever I run it, I get 1X4 syms for the values of Q,B and C_n and I get 1X1 syms for y, I want MATLAB to show me their actual values instead of this 1X4 syms ive been trying to figure it out for a while with no luck whatsoever, thanks in advance!!

To have been shown the answer in that form, you would have had to been look at the variables using the Variable Browser.
There is no way to get the Variable Browser to show the content of symbolic variables.
If you had displayed the variables to the command window, you would have seen the content.
