replace last row of a matrix in matlab

To replace the last row of a matrix in MATLAB, you can use indexing to access the last row and replace it with a new row.

Here's an example code snippet:

main.m
% create a sample matrix
A = [1 2 3; 4 5 6; 7 8 9];

% create a new row to replace the last row
newRow = [10 11 12];

% get the number of rows in the matrix
numRows = size(A, 1);

% replace the last row with the new row
A(numRows, :) = newRow;
244 chars
12 lines

In this code, we first create a sample matrix A. We then create a new row newRow that we want to replace the last row of A with.

We get the number of rows in A using the size function, and then use indexing to replace the last row with newRow.

After running this code, the matrix A will have the last row replaced with newRow.
