Hello,
I am trying to just insert a 0 into my 48x1 double vector z, like this:
array = [0.0,z]
I keep getting:
Error using horzcat Dimensions of matrices being concatenated are not consistent.
What am I missing?

@David Pesetsky: What shape do you expect the output to be, when you concatenate these together horizontally: [1x1,48x1]. The first has one row, the second has 48 rows... how many rows should the output have? How many columns?

You should join them by using vertcat. Note that your z is row matrix.
z = rand(48,1) ;
array = [0.0 ;z] % method 1
array = vertcat(0,z) % or use vertcat
