i have multiple .mat file. In each file i have several matrix data with same variable name. i want to take same matrix data from each .mat file and plot . how can i do that?

load a_D_0.mat;
load a_D_2.mat;
load a_D_4.mat;
load a_D_6.mat;
load a_D_8.mat;
load a_D_9.mat;
col_no = [51];
legends_name = ['y / D = 0.0', 'y / D = 0.2', 'y / D = 0.4', 'y / D = 0.6', 'y / D = 0.8', 'y / D = 1.0'];
length = 4000;
depth = 50;
x_start = 1500; %15.5;
x_end = 2500; %24.5;
number_of_division = 200;
x_inrement = (x_end - x_start)/number_of_division;
x_axis = x_start:x_inrement:x_end;
x_axis_wrt_midPoint = x_axis - (length/2);
x_axis_normalized = x_axis_wrt_midPoint/depth;
figure(1);
%value = SS1' ;
temp1 = load('a_D_9.mat','SS1');
temp2_1 = SS1';
temp2 = load('a_D_0.mat','SS1');
temp1_1 = SS1';
temp2_0 = temp2_1(:,col_no);
temp1_0 = temp1_1(:, col_no);
plot(x_axis_normalized, temp1_0,'b',x_axis_normalized, temp2_0,'r');

Hi Obidullah
As per my understanding, you wish to import same name matrix data from several .mat files and wish to plot them.
This is possible by using ‘load’ function and saving those data in another variable in your current workspace
Tm1= load("m1.mat","ab")
Tm2= load("m2.mat","ab")
You can later use them as per your requirement. For more information about the ‘load’ function you can refer to the documentation below
https://www.mathworks.com/help/matlab/ref/load.html
temp1 = load('a_D_9.mat','SS1');
temp2_1 = SS1';
temp2 = load('a_D_0.mat','SS1');
temp1_1 = SS1';
temp2_0 = temp2_1(:,col_no);
temp1_0 = temp1_1(:, col_no);
In your code, temp2_1 and temp1_1 has the same value and same goes with temp2_0 and temp1_0. Do check if this is what you intend on doing.
