图形完成後,我们可用axis([xmin,xmax,ymin,ymax])函数来调整图轴的范围: axis([0, 6, -1.2, 1.2]); 此外,MATLAB也可对图形加上各种注解与处理: xlabel('Input Value'); % x轴注解 ylabel('Function Value'); % y轴注解 title('Two Trigonometric Functions'); % 图形标题 legend('y = sin(x)',...

一、简介 霍夫变换(Hough Transform)是通过一种投票算法检测具有特定形状的物体。该过程在一个参数空间中通过计算累计结果的局部最大值得到一个符合该特定形状的集合作为霍夫变换结果。 霍夫变换运用两个坐标空间…
Thegcafunction can return the chart object as the current axes. You can pass the chart object to many MATLAB functions that accept an axes object as an input argument. For example, you can pass the chart object to thetitlefunction.

For example, you can specify 20% opacity by setting the MarkerFaceAlpha value to 0.20. Get bc = bubblechart(x,y,sz,'MarkerFaceAlpha',0.20); If you create the chart by calling the bubblechart function with a return argument, you can use the return argument to set properties on the ...
