Why using Text I get: "Error using text Invalid parameter/value pair arguments"?

Hello all,

I enter this line:

text(double(Cell.pos.t(idxs_walls)),double(zeros(length(idxs_walls),1)),num2str(numbering_walls_and_corners(idxs_walls)),'r'); hold on;

and I receive:

Error using text
Invalid parameter/value pair arguments

Anyone knows the reason? I watched in other topic that the reason is because of that type of X or Y is not double, but this error remains after the convert to double too...

Thanks in Advance

text(double(Cell.pos.t(idxs_walls)), double(zeros(length(idxs_walls),1)), num2str(numbering_walls_and_corners(idxs_walls)), 'Color', 'r'); hold on;

You cannot just pass a color to text() like you can to plot(); you have to tell it that the parameter refers to color.
