How to import different data in for loop ?

Hello everybody, Thank you for reading this

I have a simple code for generating efficiency map for electric machine from data file taht contains all needed variables(Speed, Shaft_Torque, Total_Loss)

%%%%%

figure;

contourf(Speed,Shaft_Torque,Total_Loss,45,'EdgeColor','none','Showtext','on');

box on;

grid on;

xlabel('Speed [rpm]','FontSize',20);

ylabel(' Torque [N.m]','FontSize',20);

%title('Rendement');

%axis([0 14000 -300 300 ]);

colorbar ('FontSize',20);

%%%%%%

Now considering that I have data files of different electric machines, I want to plot efficiency map for every machine

%Definition of different machines

Machine_1=load('M3_MSAP_hairpin_2layers_265_500_180_120');

Machine_2=load('M3_MSAP_stranded_220_450_180_120.mat');

Machine_3=load('M3_MSAP_stranded_265_450_180_120.mat');

Machine_4=load('M3_MSAP_stranded_350_450_180_120.mat');

Machine_5=load('M3_MSAP_stranded_450_450_180_120.mat');

Machine_6=load('M3_MSRB_HP_220_450_94_106.mat');

Machine_7=load('M3_MSRB_HP_265_450_94_106.mat');

Machine_8=load('M3_MSRB_HP_350_450_94_106.mat');

Machine_9=load('M3_MSRB_HP_450_450_94_106.mat');

How can I create a for loop that calls a different machine in every iteration (from 1 to 9) ?!

Thank you for your help !

Perhaps something like this:

% i'm assuming that first filename has an extension
fnames={'M3_MSAP_hairpin_2layers_265_500_180_120.mat'; ...
        'M3_MSAP_stranded_220_450_180_120.mat'; ...
        'M3_MSAP_stranded_265_450_180_120.mat'; ...
        'M3_MSAP_stranded_350_450_180_120.mat'; ...
        'M3_MSAP_stranded_450_450_180_120.mat'; ...
        'M3_MSRB_HP_220_450_94_106.mat'; ...
        'M3_MSRB_HP_265_450_94_106.mat'; ...
        'M3_MSRB_HP_350_450_94_106.mat'; ...
        'M3_MSRB_HP_450_450_94_106.mat'};

% use an array instead of a pile of variables
Machines=cell([numel(fnames) 1]);
for f=1:numel(fnames)
    Machines{f}=load(fnames{f});
end
