x1a+x2b+x3c+x4d=0

y1a+y2b+y3c+y4d=0

z1a+z2b+z3c+z4d=0

t1a+t2b+t3c+t4d=0

how this equations change to matrix? like:

Matrix(4, 4, [x1, x2, x3, x4, y1, y2, y3,y4, z1,z2,z3,z4,t1,t2,t3,t4]).Matrix(4, 1, [a,b,c,d])=Matrix(4 ,1, [0,0,0,0])

 

k^4-k^2*(4*u*m+2*q^2)+k*(8*m*E*q)+4*m^2*(D^2-e^2+(q^2/2*m-u)^2)=0
