Question

matlab 坐标系中画圆已知半径y=70和圆心点（550，,40）

Answer 1

x0 = 550, y0 = 40; %原点（550，40）
theta=0:pi/100:2*pi; %角度[0,2*pi]
R=2; %半径70
x=R*cos(theta)+x0;
y=R*sin(theta)+y0;
plot(x,y,'-')
axis equal

Answer 2

clear
clc
p = 0:3.1416*0.01:3.1416*2;
x = cos(p) * 70 + 550;
y = sin(p) * 70 + 40;
plot(x,y)
axis equal
