Issues with windscreen.B:
- it is not in valid Matrix Market format, because the array format is supposed to have only the number rows (22692) and columns (1) written in one line after the comment section, and not also the number of nonzeros as in the coordinate format (e.g. windscreen.K and windscreen.M),
- mmread.m will read this file without reporting the error, but adding an empty line immediately after the comment section (which is valid by itself) will cause mmread.m to report the error,
- scipy.io.mmread raises an exception when reading this file (removing the number of nonzeros makes it readable),
- the array format is used, even though there is only one nonzero element,
- the complex format is used, but all imaginary parts are exactly zero.
