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

Hi,
You can use the mldivide or \, for solving the same.
Refer the following link for detailed explanation,

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'
