Log Plot Using theloglog()Function in MATLAB If you want to plot the variables on a base 10 logarithmic scale on the x-axis and y-axis, you can use theloglog()function. See the below code. a=logspace(0,10);b=3.^a;loglog(a,b)grid on ...
MATLAB Online에서 열기 Sometimes using loglog does not change the scale to a logarithmic scale. h=10.^-(0:5); err=[1.4 1.04 1.004 1.0004 1.00004 1.000004]; loglog(h,err,'-o') The y-axis is not a log-scale. Indeed, using loglog(err, err) makes both axes not use a log ...
但是,有时数据会以对数刻度更自然地出现,并且使用 matlab 内置函数无法绘制此图。 简单地在速度数据上添加“日志”是行不通的,因为它会弄乱角度。 该文件将速度数据重新调整为对数,从而保持数据点之间的角度。 基于此线程: https://www.mathworks.com/matlabcentral/answers/271952-how-to-create-a-quiver-plot-...
Input power level used to plot the data using a logarithmic scale for they-axis, specified as the comma-separated pair consisting of'Pin'and a scalar in dBm.

在Matlab中,log scale即对数刻度是非常常见的,特别在信号处理和图像处理中经常会用到。log scale能够更清楚地展示出数据之间的关系和趋势,因此在实际的数据分析和处理中使用广泛。在实践中,我们经常需要对log scale进行换算,接下来我们将介绍在Matlab中如何进行log scale的换算。 二、log scale的定义 在Matlab中,log...
MATLAB Online で開く Hello, I do need to render a surf plot with log-y and log-z scaling. However, as soon as I change the axis scaling from linear to log a transparency is not possible. A small example below: [X Y Z] = peaks(40); ...
matlab % 添加标题和轴标签 title('Customized Log-Log Plot'); xlabel('X-axis (log scale)'); ylabel('Y-axis (log scale)'); 5. 保存或展示图形 最后,你可以将绘制好的图形保存为文件(如PNG、JPEG或PDF格式),或直接在MATLAB中展示。 matlab % 保存图形为PNG文件 saveas(gcf, 'log_plot.png');...
