Replace initial values of an matrix.

Hi. Good day.

Waiting for your valuable help.

I have a matrix A (4 X 4) with these initial values

A = [0.3511 1.2091 1.8834 1.5089

     0.5290 1.1016 1.7171 1.2664

     0.9242 1.5412 1.8093 1.0313

     0.5027 1.4695 2.2388 1.1906];

Matrix A is subjected to several mathematical steps and as a result a matrix B is obtained (3 X 4)

B = [0.3512 1.2999 1.8885 1.5588

     0.5299 1.1999 1.9192 1.2787

     0.9292 1.5888 1.8993 1.2589];

It is observed that matrix B is missing a line to be the same size as matrix A

How do I replace the values of matrix B in matrix A by repeating the last line of matrix B?

The new matrix A would look like this

B = [0.3512 1.2999 1.8885 1.5588

     0.5299 1.1999 1.9192 1.2787

     0.9292 1.5888 1.8993 1.2589

     0.9292 1.5888 1.8993 1.2589];

solution in general:

B=B(horzcat(1:size(B,1),repmat(size(B,1),1,size(A,1)-size(B,1))),:)

particular:

B=B([1:3 3],:)
