So i have a matrix involving summations
matrix a = [F sum(sinp) sum(cosp)
sum(sinp) sum(sin^2(p)) sum(sinpcosp)
sum(cosp) sum(sinpcosp) sum(cos^2(p)) ]
b= [ X Y Z]
c=[sum(a) sum(asinp) sum(acosp)
how would i include the summations in the matrix
and how would I then be able to solve the matrix in terms of X Y Z

Original Question: "solving ax=b for x"

sum(cosp) sum(sinpcosp) sum(cos^2(p)) ]

Can you elaborate what you meant by including summation in matrix. If your problem is to solve a*b' = c', then you can find b', from a\c'
