how to select rows in array in matlab

To select specific rows in an array in MATLAB, you can use indexing. Here's an example to demonstrate how you can select rows with specific indices:

main.m
% Create an example matrix
A = [1 2 3; 4 5 6; 7 8 9; 10 11 12];

% Select rows 2 and 4
selectedRows = A([2, 4], :);

% Display selected rows
disp(selectedRows);
161 chars
9 lines

In this example, A([2, 4], :) selects rows 2 and 4 from the matrix A. The colon (:) after the comma is used to select all columns. You can modify the row indices inside the square brackets according to your requirements.
