Obtaining a value from det()=0 equation

Hi guys I need to obtain the parameter w from this huge 8*8 matrix that its det is 0. (I should find the mode shape of a vibrational system just to let you know)

But the problem is that m1, m2, alpha1, alpha2, etc depend on w as well and so I can't even define the matrix.

Because of being a MATLAB noob, I tried defining w by linspace and then other parameters through it but when I want to define matrix components I receive an error obviously because, for example, I can't define component (2,2) because m1 is a matrix itself.

Should I use bvp or something of that ilk?
