How can i make a matrix with variables from workspace.

8 views (last 30 days)
I have made a matrix and saved the matrix lines seeratly, as for example: line1, line 2, line 3
How can I write a for loop for creating a matrix, where the programm asks which lines i want o include in my new matrix.
%Those lines are saved as a vector

The MATLAB approach is to use an index:
idx = [2,4,11]; % indices of the rows you want
out = simulink_matrix(idx,:);
Your current approach (with lots of numbered variables) will make this task slow, complex, and very inefficient.

Hi Marcais,
As Stephen mentioned in one of the comments, creation of numbered variables would be an in-efficient approach. However as you mentioned that, you want the program to ask the lines which you want to include in the output, I can recommend using the "input" keyword inside a for loop and then perform the related options accordingly. You can check the follwing code for reference
You can check the documentation for input here.
