assign column of struct to variable in matlab

To assign a column of a struct to a variable in MATLAB, you first need to access the field containing the column by using dot notation. Then you can use the column indexing to extract the desired column and store it in a variable.

Here's an example code snippet that will assign the second column of a struct array called data to a variable col:

main.m
% create example struct array
data(1).col1 = [1 2 3];
data(1).col2 = [4 5 6];
data(2).col1 = [7 8 9];
data(2).col2 = [10 11 12];

% assign second column of data(1).col2 to variable col
col = data(1).col2(:,2);

% display contents of col
disp(col);
248 chars
12 lines

In this example, the : operator is used to return all rows of the second column. The output of the code will be:

main.m
5
11
5 chars
3 lines
