Hi Bidyarani,

You can make use of load function to read the .mat file into MATLAB.

Below is the sample code for that:

filename = 'test.mat';
load(filename)

You can read more about the load function here: Load variables from file into workspace

Hope this helps!

Thank you @Kunal Kandhari. It works.

i am trying to display all the variables along with the values using code shown below.

filename = 'durer.mat';
myVars = {'d_users','cellular_users','pathloss_users','pathloss_cellular'};
S = load(filename,myVars{:})
disp(S)

Not able to display all variables.

and if i give disp command for one variable which is shown below

disp(cellular_users)

it displays all the values of the variable "cellular_users" which is 499X499 size but the thing is all the values turn out to be zero.

can you please help me out with this?

Can you please try this out:

In command window, run this command:

clear

it will clear your workspace and then run the following code:

myVars = {'d_users','cellular_users','pathloss_users','pathloss_cellular'};
load(filename,myVars{:})
disp(cellular_users)

And let me know the output

@Kunal Kandhari thanks. It works. The values of the variables are displayed correctly.
