Question

我正在使用一些处理数据的matlab代码（在卡尔曼滤波器中）并创建一系列等高线图。它已经在matlab 2006a上的RHEL 4服务器上运行了几年，但我的老板最近要求所有服务器都更新到RHEL 6 ...至少matlab 2007a。我已经计算出这些版本之间的所有折旧，但我仍然遇到一个主要问题。

创建和打印不同等高线图的代码适用于首先创建的三个图中的任何一个。它看起来像这样： enter image description here

不幸的是，接下来的两个情节看起来像这样：

enter image description here

这三个数字在不同的函数中独立绘制，我在创建每个数字之前和之后使用clf("reset");。每个函数本身都可以工作，但是当绘制所有三个函数时，第二个和第三个数字都搞砸了。有没有其他人有这个问题？这是创建其中一个数字的代码。

function Crd = TEC_plot(ITEC,RT,Param,Input,t,OutPath,RxExtAll,Time)
% Generate TEC plot 
    Function_for_Spline_Smoothing = [.05 .1 .05; .1 .4 .1; .05 .1 .05];
    ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
    ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother
%   ITEC = conv2(ITEC,Function_for_Spline_Smoothing,'same'); % add more of these lines to make contours smoother

Answer 1

尽量不要使用clf来清除你的整个数字，但使用中间的figure来打开三个独立的数字。看到它会起作用：）

编辑：这只是猜测而没有真正看到你的代码

Answer 2

一个猜测可能是生成最终PNG文件的代码。从JPG转换为PNG时，您的第二个数字似乎被错误裁剪。

首先修复print命令以使用图1中的任何内容。因此，为确保使用图1进行绘图，请使用命令figure(1)来指定此项。或者，将打印命令更改为阅读print(gcf ...以打印当前图形。

另请注意，您可以使用{/ 1}}直接生成PNG文件，如

print

并跳过从PS到JPG到PNG步骤的转换。

对print(gcf,'-dpng','-r1000',filename(...))中的图形窗口进行硬编码可以解释为什么事情可以独立工作，但如果你有多个数字窗口，那么就不能一起工作。只是一个猜测。

在Matlab中绘制多个数字
