You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: get_loss_map.m
    path of file: ./repos/AI-mag/resources/material_database/utils
    
    the code of the file until where you have to start completion: function P_mat = get_loss_map(data_map, data_bias, param, interp)
% Combine the AC and DC loss map and get the loss value of the specified points.
%
%    Parameters:
%        data_map (struct): main loss map
%        data_bias (struct): loss map for DC bias correction (if required)
%        param (struct): parameters for the interpolation method
%        interp (struct): point to interpolate (frequency, AC fl
    
function fact = get_interp_bias(data, f, B_ac_peak, B_dc, T, extrap)
% Interpolate the correction factor for the DC bias.
%
%    Parameters:
%        data (struct): loss map
%        f (matrix): frequency matrix
%        B_ac_peak (matrix): AC flux density matrix
%        B_dc (matrix): DC flux density matrix
%        T (matrix): temperature matrix
%        extrap (struct): extrapolation data
%
%    Returns:
%        fact (matrix): multi-dimensional matrix with the correction factor for the DC bias

% interpolation
P_ac = get_interp(data, f, B_ac_peak, 0.*B_dc, T, extrap);
P_dc = get_interp(data, f, B_ac_peak, 1.*B_dc, T, extrap);

% correction factor and clamp
fact = P_dc./P_ac;
fact = get_clamp(fact, extrap.fact);
