Hi, Matlab Community.
I wanna ask, about the output of my code below :
%a) Find The Least Square Lines (Polynomial) That Best Fits On The Data On The Table
x = [2:2:12]; %Declare x matrix
y = [3.9572, 4.4854, 5.8003, 6.1419, 7.4218, 8.9157]; %Declare y matrix
masukkan = double(input('Input predictor functions orde :'));
orde = string(masukkan);
coefficient = polyfit(x, y, masukkan);
xc = [2:0.0001:12]; %Mendeklarasi Variabel xc sebagai input fungsi polyfit orde 1
yfit = polyval(coefficient, xc);
disp(sprintf("Dengan menggunakan Polyfit Orde ke %s, nilai y nya adalah %.3f", char(orde), yfit)); %<This code's output
%are always looping (why??)
curve = figure( 'Name', 'Penentuan Best Fit Least-Square Line dari Data X dan Y dengan Polyfit Orde 1' );
plot(xc, yfit, 'Color', 'w', 'LineWidth',1.1);
hold on
plot(x, y, 'mo', 'MarkerFaceColor',[0.6 0.6 1], 'MarkerSize',5.5);
hold off
set(gca,'color',[0.4 0.4 0.4]);
title(sprintf('Best-Fit Least Square Line menggunakan Fungsi Polyfit (Polinomial Orde ke %s)', orde), 'fontweight','bold','fontsize',15.5);
xlabel('Data x','fontweight','bold','fontsize',14);
ylabel('Data y', 'fontweight','bold','fontsize',14);
legend(sprintf('Best Fit Least Square Polynomial Line (Orde ke %s)', orde), 'Data x vs y pada soal', 'Location', 'NorthWest', 'Interpreter', 'none', 'Parent', curve, 'color', 'c', 'fontsize',12);
grid on;
The plotting part is good, but the output of disp function of input function (masukkan variable) is looping to infinite until it is said :
Output truncated. Text exceeds maximum line length for Command Window display.
The input function is only declare 1 variable (our keyboard number0 but why the result is such a looping of sprintf?
Thank you everyone /.\ /.\ /.\

The expected output is repeated a zillion times, because yfit is a vector with a zillion elements
>> whos yfit
Name Size Bytes Class Attributes
yfit 1x100001 800008 double
