How can I change this trajectory?

Hello everybody

I want to change the code in spiral.m file so that it creates a spiral shape like this picture(which red stars are on it) with the same range and these additional lines on the corners.

Thanks in advance.

The axis range of the plot can be set using 'axis' in MATLAB. For example, to achieve the axis limits shown in the attached figure:

axis([0 100 0 100]);

Refer to the MATLAB documentation for a clear description and examples. To answer the second question about getting the markers, use the * Marker symbol. For more information and examples, please refer to the plot documentation.
