How to store a field of 1x5 structure in a variable(array) in MATLAB?

Question

I want to store all values of a field of a 1x5 structure in a variable(array) in MATLAB... See the attached screenshots for better understanding.

Answer 1

Dot-Indexing by Field Name and Formatting as an Array

To access the specific field dot indexing by the structure, I by the field name in this case Overshoot can be done. To format this as an array the square brackets [] can be used to convert the cell array to a row vector. To convert this to a column-vector like how it appears in structure, I we can transpose this by using the .' term.

Overshoot = [I.Overshoot].';

Test Script:

%Random structure to test%
I(5).RiseTime = [];
I(5).SettlingTime = [];
I(5).SettlingMin = [];
I(5).SettlingMax = [];
I(5).Overshoot = [];
I(5).Undershoot = [];
I(5).Peak = [];
I(5).PeakTime = [];

%Filling the random structure%
for Index = 1: 5
    I(Index).RiseTime = rand(1,1);
    I(Index).SettlingTime = rand(1,1);
    I(Index).SettlingMin = rand(1,1);
    I(Index).SettlingMax = rand(1,1);
    I(Index).Overshoot = rand(1,1);
    I(Index).Undershoot = rand(1,1);
    I(Index).Peak = rand(1,1);
    I(Index).PeakTime = rand(1,1);
end

Overshoot = [I.Overshoot].';
