The present code is a Matlab function that provides interactive selection of a data section from a 2D plot using vertical mark lines. The function is very suitable for GUI developments or interactive selection and saving 2D data plot sections. The user can position each of the two vertical mark lines in an interactive mode, using the mouse – double click of the left mouse button place the first line, double click of the right button place the second line. After that, one must press “Enter” keyboard key in order to save the selected 2D plot (between the two lines) as a .mat data file – abscissa values are placed in the first matrix column and the ordinate values – in the second one. The interactive mode can be stopped using the “End” keyboard kay.
An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.
