TXT文件名的格式为E_Field10.txt 、E_Field20.txt ......E_Field4000.txt .

记录的一个平面的场分布

 

% input the base file name
f = 'E_Field';

% input the total number of iterations
n = 4000;

% input the value of time step
k = 10;

%Input x axis label
xAxisLabel = 'Y';
%Input y axis label
yAxisLabel = 'X';

%Input Plot title
graphTitle = 'E Field';

% index variable for Movie
i = 1;

% movie initialization
M = moviein(n / k);

% loop n / k times
for m = k : k : n

    % full file name
    file = [f '_' int2str(m) '.txt'];

    % load the file to A
    A = load(file);

    % pseudocolor plot
    pcolor(A);

    % a color bar
    colorbar;

    % set equal size tick marks
    axis image;

    % Min & max value for color code
    caxis([-1e-1 1e-1]);

    % shading in interpolated format
    shading interp;

     % set label for x axis
    xlabel(xAxisLabel);

    % set label for y axis
    ylabel(yAxisLabel);

    % title of the plot
    title([graphTitle, ' At Time Step = ', int2str(m)]);

    % store the frame for movie
    M(:, i) = getframe;

    % increment movie frame index
    i = i + 1;

% end of loop
