okay when if its okay with u ill write post the instructions so it be clearer than me explaing\
By calling the function smatrix(A,x,n),with n=4,
which you will construct, determine the components of the matrix A_s=(A+A_t)/2, where
A_t stands for the transpose matrix of A, and the components of the
vector y=(A_s*x)/norm_x, where norm_x denotes the norm (length) of the vector x.
Print the components of the matrix A_s and the vector y in the main.
