Bresenham直线算法GUI——matlab实现

话不多说，直接上代码
BresenhamLine.m

function BresenhamLine(x0,y0,x1,y1) dx=x1-x0; dy=x1-x0; len=max(abs(x1-x0),abs(y1-y0)); d(1)=dx-2*dy; up=2*dx-2*dy; down=-2*dy; x(1)=x0; y(1)=y0; for n=1:len x(n+1)=x(n)+1; if d(n) < 0 y(n+1)=y(n)+1; d(n+1)=d(n)+up; else y(n+1)=y(n); d(n+1)=d(n)+down; end end for n=1:len plot(x,y); end function BresenhamLine(
