how i can find this in MATLAB in order to find (τ,ν): I want the code and i will fix it

(τ,ν)= argmax(τ,ν) ​xp^H ​A(τ,ν) (A(τ,ν)^H A(τ,ν))−1 A(τ,ν)H xp

how i can find this in matlab

note: all coefficients are vector

xp is a given vector ? A is a matrix with elements depending nonlinearly on tau and nu ?

A few more explanations may help to get a useful answer.
