Some variable can be set by block that expands this org source code block:

• path: specify the path of the figure including the file extension. Can be relative or absolute. If not provided, it will create the figure in the /tmp folder
• fig_size: can specify the size of the figure. If not specify, default will be applied.

if ~exist('filepath') || length(filepath) < 2
  symbols = ['a':'z' 'A':'Z' '0':'9'];
  random_string = symbols(randi(numel(symbols),[1 5]));
  filepath = ['/tmp/matlab-fig-', random_string];
end

size_strings = strsplit(figsize, '-');
