I have a set of functions in an array, and need to call specific functions from within an array so that I can graph them. But if I index a specific row of the array, but a function will only allow one expression. Below is an example of what I am trying to do.
A(x)=[x,2x,3x;4x,5x;6x]
B=A(1,:)
Where it should be B=[x,2x,3x]. But this will give me an error. I need to graph the functions in the rows, so I can't just call the values at a specifc x and then take the value after the fact.
Suggestions?

h_matrix = @(x)(x*[1 2 3;4 5 6]);
A = sym(h_matrix);
B = A(1,:);
