Description
When using the fTools plugin, 'Vector -> Analysis Tools -> Distance Matrix', if 'Summary Distance Matrix' is chosen with 'Use only the nearest (k) target points' and the value of '1' is chosen, the plugin crashes. I attached a file with a minor modification of how to fix the function def linearMatrix(), but I'm not sure how to connect to the code repository, or if it follows the correct conventions.
Here is the error message:
An error has occured while executing Python code:
