I have a 3×3 matrix of values ex
A=[ 1 2 3;
4 5 6;
7 8 9]
I need it to add zeros at certain locations with in the matrix to make a 5×5 with zeros in the 3rd and 4th row and column ex
A2=[1 2 0 0 3;
4 5 0 0 6;
0 0 0 0 0;
0 0 0 0 0;
7 8 0 0 9]
my first attempt was concatenate but I can't figure out how to move the values correctly
newA=[A,zeros(3,2)]
newA_1=[newA;zeros(2,5)]
