MATLAB: How do i get the graph plotted

for loopgraph

hold on
for x=0:0.01:pi
      y=sin(x);
      plot(x,y)
      grid on
      grid minor
  end

Best Answer

With a few changes, it works:

hold on
x=0:0.01:pi;
for k1 = 1:length(x)
    y(k1)=sin(x(k1));
end
plot(x,y)
grid on
grid minor

See plot():

x = 0:0.01:10;
y = sin(x)./x
plot(x, y);

MATLAB: Plot is over plotted

x = 1:10;   % No need for square brackets
y = sin(x);
for k = 1:10
  % NextPlot='add' is the same as "hold on"
  AxesH(k) = subplot(10, 1, k, 'NextPlot', 'add');
end
x2 = 1:0.01:10;
for i = 10:10:100
  for j = 1:10
    p  = polyfit(x,y,i);
    y2 = polyval(p,x2);
    plot(AxesH(j), x,y,'o', x2,y2,'-b');
  end
end

subplot clears formerly existing axes objects. So create the axes at first and use them as parent object as first input to plot.
