Display Parameter with Properties in Command Window

Hello,

I would like to loop through the variables in my Workspace and display the properties of certain variables in the Command Window. Using "whos", I can loop through all the variables and filter them as I desire:

tempvar_s = whos;

for tempvar_i = 1:length(tempvar_s)
    % Include any filters here in the IF statement clauses
    if (strcmp(tempvar_s(tempvar_i).name, 'tempvar_s')) || (strcmp(tempvar_s(tempvar_i).name, 'tempvar_i')) || (strcmp(tempvar_s(tempvar_i).name, 'tempstrFileName'))
        % do nothing
    else
        disp(tempvar_s(tempvar_i).name)
        disp(tempvar_s(tempvar_i))
    end
end

My problem is that when I use the "disp" command to display the variable using my script, I get the structure from whos, like in the following example:

p1_kPa
          name: 'p1_kPa'
          size: [1 1]
         bytes: 112
         class: 'Simulink.Parameter'
        global: 0
        sparse: 0
       complex: 0
       nesting: [1x1 struct]
    persistent: 0

But if I type the same example variable into the Command Window and hit enter, I get a different list:

p1_kPa = 

    Parameter with properties:

            Value: 101.3250
        CoderInfo: [1x1 Simulink.CoderInfo]
      Description: 'Ambient pressure in kPa'
         DataType: 'single'
              Min: 0
              Max: 1000
         DocUnits: 'kPa'
       Complexity: 'real'
       Dimensions: [1 1]

Can anyone advise how I can get my script to print out the second data set rather than the first?

This is an expected behavior because when you use 'tempvar_s = whos' command in your script, you are saving specific information about the workspace variables into a structure array named 'tempvar_s'. This struct has the fields like name, size, bytes etc.

In order to display the dataset similar to the second one rather than the first, you can try using a script similar to this:

a = 4;
p1 = Simulink.Parameter;
save test.mat a p1
x = load('test.mat')
x.p1

Vishal, thank you for the reply. Unfortunately this still doesn't help me as I can't loop through all the variables with this approach, correct? I have to manually type each variable name.
