在八度/ Matlab中绘制图表数组而不使用for循环

Question

How can I plot an array of plots all at once without using a for loop ?

Example code below:

clear all,clf reset,tic,clc 

plot_array_x1=[-0.1732050807568878  -0.6767949192431123  -1.366025403784439
  0.1732050807568877  0.176794919243112  0.366025403784438
  6.123233995736766e-17  0.5000000000000001  1];

plot_array_y1=[-0.09999999999999995  0.186602540378444  0.366025403784439
  -0.1000000000000001  -0.6794228634059948  -1.366025403784439
  0.2  0.4928203230275509  0.9999999999999998];

for ii=1:3
  plot(plot_array_x1(ii,:),plot_array_y1(ii,:))
  hold on
end

The code produces the plot below but it requires me to use a for loop is it possible to avoid using a for loop?

Answer 1

You're almost there. First, transpose the arrays and then remove the loop.

plot_array_x1=[-0.1732050807568878  -0.6767949192431123  -1.366025403784439;
  0.1732050807568877  0.176794919243112  0.366025403784438;
  6.123233995736766e-17  0.5000000000000001  1].';

plot_array_y1=[-0.09999999999999995  0.186602540378444  0.366025403784439;
  -0.1000000000000001  -0.6794228634059948  -1.366025403784439;
  0.2  0.4928203230275509  0.9999999999999998].';

figure(1)
plot(plot_array_x1,plot_array_y1)
