錯(cuò)誤使用 matlab.graphics.internal.newplotwrapper 嘗試將 SCRIPT newplotwrapper 作為函數(shù)執(zhí)行: C:\Program Files\Polyspace\R2020a\toolbox\matlab\graphics\+matlab\+graphics\+internal\newplotwrapper.m怎么解決

應(yīng)該是動(dòng)了newplotwrapper的內(nèi)部代碼

解決：

1. 找到您的Matlab安裝文件夾。在Windows上，默認(rèn)情況下位于C:\Program Files\MATLAB\<MATLAB版本>。

2. 打開(kāi)toolbox\matlab\graphics\@matlab\graphics\internal文件夾。在該文件夾中，您可以找到名為newplotwrapper.m的文件，這是Matlab中的newplot函數(shù)的實(shí)際實(shí)現(xiàn)。

3. 更改為：function axReturn = newplot(hsave)
   %NEWPLOT Prepares figure, axes for graphics according to NextPlot.
   % H = NEWPLOT returns the handle of the prepared axes.
   % H = NEWPLOT(HSAVE) prepares and returns an axes, but does not
   % delete any objects whose handles appear in HSAVE. If HSAVE is
   % specified, the figure and axes containing HSAVE are prepared
   % instead of the current axes of the current figure. If HSAVE is
   % empty, NEWPLOT behaves as if it were called without any inputs.
   %
   % NEWPLOT is a standard preamble command that is put at
   % the beginning of graphics functions that draw graphs
   % using only low-level object creation commands. NEWPLOT
   % "does the right thing" in terms of determining which axes and/or
   % figure to draw the plot in, based upon the setting of the
   % NextPlot property of axes and figure objects, and returns a
   % handle to the appropriate axes.
   %
   % The "right thing" is:
   %
   % First, prepare a figure for graphics:
   % Clear and reset the current figure using CLF RESET if its NextPlot
   % is 'replace', or clear the current figure using CLF if its
   % NextPlot is 'replacechildren', or reuse the current figure as-is
   % if its NextPlot is 'add', or if no figures exist, create a figure.
   % When the figure is prepared, set its NextPlot to 'add', and then
   % prepare an axes in that figure:
   % Clear and reset the current axes using CLA RESET if its NextPlot
   % is 'replace', or clear the current axes using CLA if its NextPlot
   % is 'replacechildren', or reuse the current axes as-is if its
   % NextPlot is 'add', or if no axes exist, create an axes.
   %
   % See also HOLD, ISHOLD, FIGURE, AXES, CLA, CLF.
