Hello,
I am trying to figure out what command I can use to add a row into an array by referencing that array.
An example, I want to have a reference array A = [1 1; 1 1; 1 1]
and I want to add [0, 0] into A such that
B = [1 1; 0 0; 1 1; 1 1]
by doing some sort of command that relates B to A but adds in that [0 0] into any row I want to add it to.
Such as B = A(2,[0 0]) but this is where I am stuck
Thank you

Try this:
A = [1 1; 1 1; 1 1] % Initial array.
rowToInsert = 2;
rowVectorToInsert = [0, 0];
B = [A(1:rowToInsert-1,:); rowVectorToInsert; A(rowToInsert:end,:)]
