Inverse of a trace based function?












0












$begingroup$


I have the following linear operator:
enter image description here
and I need to compute its inverse operator enter image description here for y: vector of real values.
enter image description here



The trace function is invertible as far as I know, so is this even possible? and if so, how can I compute the inverse operator in this case?

    What do we know about the $a_m$?

    a_{m} is a vector of Nx1 that I have computed. More can be found here: paper

    And how are we meant to interpret $tr{a_ma_m^HC}$? Is the output an array of values? If so, how many values are in the array?

    By the way, you can format things mathematically by putting things between $'s. For instance, typing $Theta:Bbb C in C^{N times N}$ results in $Theta:Bbb C in C^{N times N}$
