solving ax=b for x

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

Maybe it's best for you if you try calculating each element of matrices A and C and then plug them in respective matrix. Refer to documentation on 'sum'.
Then you can use mldivide as Sai pointed it out.

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

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'
