Function variable output name to be the same as input variable name + "_pos".mat

Hello,

I have a function to do stuff, the input of the function is a matrix array with name X, I call this function several times using different inputs and I want to save the result in a mat file where the variable name will be the same as the input name variable and the .mat name the same name as the input name + "_pos".

function [position]= position_min(X)
  function code blablabla
  position = some matrix result
  save ('Posicion_min', 'position')*
end

Where X would be Mx and then My and so on, I call it like this

position_min(MxTB_min_etm)

This saves variable position under Posicion_min.mat. I want to save variable position change the name to "MxTB_min_etm _pos" and save as MxTB_min_etm_pos.mat
