What does this command line mean? (matrix A =[A t])

Hi. I was reading a MATLAB code (a numerical simulation), then I found this line that I can't understand) >>

%Let t be a scaler taken the value 5

t=5
A =[A t]

%the result on matlab was "Error using horzcat"

Could someone explain it to me please?

It means, if A is a row vector, that the value of t is to be stitched onto the right side of row vector A to form a new row vector A.

Or it could mean, if A is a scalar (single number) that the value of t (which is 5) is to be stitched onto the value of A to form a new A that is a 2-element row vector.

Square brackets can be used to concatenate arrays.
