第一步:我们需要使用plot命令绘制一个图形,绘制图形的MATLAB程序代码如下: a= [0:0.2:30]; b= cos(a); plot(a, b) 我们将此代码添加到MATLAB中,如下图所示。第二步:然后运行我们的作图程序,得出的运行结果如下图所示。图形上面什么标识标注都没有,很难明白画的图形的含义。第三步:我 1、打开MATLAB的pl...
I need to scale both axis of one 2D graph for export it. I am trying to plot force vs displacement (x), and I am asked to print the plot, following this scale: 1000 N should be 175mm 1m of displacement, should be 135mm
改变窗口大小用set这个命令,一个简单的例子见下:t = 1: 10;y = 3*t;figure(1);plot(t,y,'x-r');hFig = figure(1);x = 10;y = 220;width = 1000;height= 260;set(hFig, 'Position', [x y width height]);另外,axis是在已经生成的窗口内改变轴的范围,不是一个概念;"axis 一般而言,做完...

loglog(X,Y) plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and the y-axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at...
semilogx(X,Y) plots x- and y-coordinates using a base-10 logarithmic scale on the x-axis and a linear scale on the y-axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set...

调整线条样式可用plot(x,y,’r–’)。字母r代表红色，双短横线设定虚线样式。尝试不同组合：’b:’显示蓝色点线，’g-.o’生成绿色点划线并带圆形标记。线宽参数通过’LineWidth’设置，如plot(x,y,’LineWidth’,3)加粗三倍。配置坐标轴需调用axis函数。axis([012 -1.51.5])限定横纵坐标范围。xlabel(’...
