Question

1. Plotting a target sign Make a new script called CTask1p1.m to draw a simple target sign, as shown below. You may use sin(), cos() and line() functions, but not viscircles() function. You may use plot function's name-value pairs to specify the line width and colour. When specifying colours, you can use the colour names (or colour code), such as 'blue', 'red', instead of providing RGB vector. In addition, you can use axis equa 4 3.5 3 2.5 2 1.5 0.5 0 h -0.5 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5

Answer 1

SOLUTION:-

BY USING MAT LAB CODE:-

tutorialspoint GNU Octave 3.6.4 Execute main.m 1 clc 2 clear all 3 th-0:0.01:2 pi+1; 4 x-13cos (th) 5 y-1 sin(th); 6 plot(x,y, Linekidth',24, 'Color, 'blue); 7 hold on x-0.1*cos (th); 8 9 y-0.1 sin(th); 10 plot(x,y, LineWidth',40, Color, 'red); 11 hold on; 12 plot(linspace (-2,2,100),linspace(0,0,100), --c); 13 hold on; 14 plot (linspace(0,0,100),1inspace(-2,2,100),--c) 15 hold off; 16 axis equal 17 ylim I-2,2])
