Can I save all the xstats and ystats of a specific figure without doing it manually? I can currently do it by opening each figure, going to tools, data statistics and save to workspace on data1, data2,... There must be a better way than doing it manually.

在 MATLAB Online 中打开

You can create a function to collect this data for you. To create a structure with the same format as Tools -> Data Statistics from the figure menu, the following function can be used:

function data_stats = getDataStats(data)
  % This function gets the data statistics that can be found in the figure menu: 
  % Tools -> Data Statistics
  %
  % SYNTAX
  %  stats = getDataStats(data)
  %
  % INPUTS
  %  data: a vector containing the data to get statistics for
  %
  % OUTPUTS
  %  data_stats: A structure containing the same information from 'Data Statistics' 
  data_stats.min = min(data);
  data_stats.max = max(data);
  data_stats.mean = mean(data);
  data_stats.median = median(data);
  data_stats.mode = mode(data);
  data_stats.std = std(data);
  data_stats.range = data_stats.max - data_stats.min;
end
