将matlab中的代码：f = figure(1); set(f, 'Position', [550 68 560 700]); view(-90, 90); 转成python代码

以下是将matlab中的代码：f = figure(1); set(f, 'Position', [550 68 560 700]); view(-90, 90); 转成python代码的方式：

import matplotlib.pyplot as plt

fig = plt.figure(1)
fig.set_size_inches(5.625, 7)
ax = fig.add_subplot(111, projection='3d')
ax.view_init(elev=-90, azim=90)

其中，plt.subplots的第一个参数表示子图的行数，第二个参数表示子图的列数，第三个参数表示子图的编号。fig.set_size_inches的参数表示的是图表的宽度和高度，单位是英寸。ax.view_init中的参数表示的是视角的方位、高度。

优化这段代码 让它输出可以改变坐标轴大小的图像形式 % plot_Bscan.m % Script to plot EM fields from a gprMax B-scan % % Craig Warren clear all, clc [filename, pathname] = uigetfile('*.out', 'Select gprMax output file to plot B-scan', 'MultiSelect', 'on'); filename = fullfile(pathname, filename); % Open file and read fields if filename ~= 0 iterations = double(h5readatt(filename, '/', 'Iterations')); dt = h5readatt(filename, '/', 'dt'); prompt = 'Which field do you want to view?

改进后的代码如下：

% plot_Bscan.m
% Script to plot EM fields from a gprMax B-scan
% Craig Warren

clear all, clc

[filename, pathname] = uigetfile('*.out', 'Select gprMax output file to plot B-scan', 'MultiSelect', 'on');
filename = fullfile(pathname, filename);

% Open file and read fields
if filename ~= 0
    iterations = double(h5readatt(filename, '/', 'Iterations'));
    dt = h5readatt(filename, '/', 'dt');

    prompt = 'Which field do you want to view? Ex, Ey, or Ez: ';
    field = input(prompt,'s');
    fieldpath = strcat('/rxs/rx1/', field);
    field = h5read(filename, fieldpath)';
    time = linspace(0, (iterations - 1) * dt, iterations)';
    traces = 0:size(field, 2);

    fh1=figure('Name', filename);
    clims = [-max(max(abs(field))) max(max(abs(field)))];
    im = imagesc(traces, time, field, clims);
    xlabel('Trace number');
    ylabel('Time [s]');
    c = colorbar;
    c.Label.String = 'Field strength [V/m]';
    ax = gca;
    ax.FontSize = 16;
    
    % Options to create a nice looking figure for display and printing
    set(fh1,'Color','white','Menubar','none');
    X = 60;   % Paper size
    Y = 30;   % Paper size
    xMargin = 0; % Left/right margins from page borders
    yMargin = 0;  % Bottom/top margins from page borders
    xSize = X - 2*xMargin;    % Figure size on paper (width & height)
    ySize = Y - 2*yMargin;    % Figure size on paper (width & height)

    % Figure size displayed on screen
    set(fh1, 'Units','centimeters', 'Position', [0 0 xSize ySize])
    movegui(fh1, 'center')

    % Figure size printed on paper
    set(fh1,'PaperUnits', 'centimeters')
    set(fh1,'PaperSize', [X Y])
    set(fh1,'PaperPosition', [xMargin yMargin xSize ySize])
    set(fh1,'PaperOrientation', 'portrait')
    
    % Allow user to adjust axis limits
    prompt = 'Do you want to adjust the axis limits? (y/n): ';
    response = input(prompt, 's');
    if response == 'y'
        prompt = 'Enter the lower limit for the y-axis: ';
        yLow = input(prompt);
        prompt = 'Enter the upper limit for the y-axis: ';
        yHigh = input(prompt);
        ylim([yLow, yHigh]);
    end
end

改进的部分是添加了一个可以让用户调整坐标轴大小的选项。当程序运行时，它会询问用户是否要调整y轴的范围，如果用户输入'y'，则程序会提示用户输入y轴下限和上限。然后使用ylim函数将y轴的范围设置为用户输入的值。

这是一个 MATLAB 脚本，用于绘制 gprMax 模拟数据的 B-scan 图像。用户需要选择一个输出文件，然后指定要查看的场强量（Ex，Ey 或 Ez），脚本将读取相应的数据并生成图像。图像中的 x 轴表示探测器（rxs）的测量位置，y 轴表示时间，颜色表示场强。此外，该脚本还提供了一些选项，用于创建漂亮的图像以供显示和打印。
