what I intend to do is print the polynomial without variables and somehow I would like to add it in a textual way, that is, I do not know something like set (handles.edit9, get (handles.edit10, 'string') 'x') is an idea vague but can you do something like that?

在 MATLAB Online 中打开

numeric_coefficients_in_descending_order_of_power = ....   %row vector!
power_list = length(numeric_coefficients_in_descending_order_of_power)-1 : -1 : 0;
result = strjoin( sprintfc('%d * x^%d', [numeric_coefficients_in_descending_order_of_power; power_list].' ), ' + ');
