MATLAB: Insert first element into existing column vector…

Question

Hello,

I am trying to just insert a 0 into my 48×1 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?

Answer 1

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
