how to combine a matrix that is one row with another matrix in matlab

To combine a matrix that is one row with another matrix in MATLAB, you can use the concatenation operator [].

Here's an example of how to do it:

main.m
% Define the first matrix
matrix1 = [1, 2, 3];

% Define the second matrix
matrix2 = [4, 5, 6;
           7, 8, 9];

% Combine the two matrices
combinedMatrix = [matrix1; matrix2];

% Display the combined matrix
disp(combinedMatrix);
234 chars
13 lines

The [] operator is used to concatenate matrix1 and matrix2, where matrix1 is a row matrix and matrix2 is a multi-row matrix. The resulting combinedMatrix will have matrix1 as its first row, followed by matrix2.

Output:

main.m
    1     2     3
    4     5     6
    7     8     9
54 chars
4 lines

Note: Make sure the number of columns in matrix1 matches the number of columns in matrix2, otherwise MATLAB will display an error.
