how to plot like the following figure( i need code)

You need to get the coordinates of each data, for example, in the green curve (TSMF) the data are : (5,50),(10,100),(20,250) ... so on and so forth. Remeber each point has the coordinate (x,y).

points_coords = [5 50;10 100;20 250;30 650;40 1500;50 3500]; % is a matrix of 6x2 
x = points_coords(:,1);             % the colon symbol in the firs potition selects every row, and the "1" the first column
y1 = points_coords(:,2);
plot(x,y1,'g-^')                    % the 'g-^' g = green (color) - = solid line (line type) ^ = generates triangles (marker)

As you can see is only a curve. You need to add the corresponding points within the points_coords varibale and generates new variables y2, y3 .... yn. For more information about the parameters to plot the other curves visit the plot function documentation. You can olso visit: xlabe, ylabel, title and legend commands.

Yes, that's right. But now we have the data is more easier.

x = 10:10:90            % the colon operator allows define a vector on a range with increments initial:increment:final
MSE_values = [5.9392, 7.3934, 10.2113, 13.6319, 17.0441, 21.9598, 28.1901, 35.3217, 47.1861;
              15.3395, 32.8796, 48.0746, 75.7206, 117.3670, 152.2416, 220.0498, 262.7240, 357.6435]
y = MSE_values'; % the ' symbol carries out the transpose of a matrix (is to say, change rows by columns and columns by rows)
hold on         % hold on comand allows plot multiplecurves at the same time  
grid on         % grid on comand shows the grid over the plot
plot(x, y(:,1),'b-o');  % plot the A curve in color blue and marker o in a solid line
plot(x, y(:,2),'g-^');  % plot the F curve  in color green and marker triangle in a solid line
legend ('A','F') % add legend at the plot

The code above produces:

x =

10 20 30 40 50 60 70 80 90

MSE_values =

5.9392 7.3934 10.2113 13.6319 17.0441 21.9598 28.1901 35.3217 47.1861

15.3395 32.8796 48.0746 75.7206 117.3670 152.2416 220.0498 262.7240 357.6435

y =

5.9392 15.3395

7.3934 32.8796

10.2113 48.0746

13.6319 75.7206

17.0441 117.3670

21.9598 152.2416

28.1901 220.0498

35.3217 262.7240

47.1861 357.6435

Now you have to add the missing values over the MSE_values matrix, then add more plot function for the other curves, for example

plot(x,y(:,3));
plot(x,y(:,4));
.
.
. 
plot(x,y(:,n))

Finally change the legend comand adding the names of the missing cuvers.
