`scipy.io.matlab._mio4:MatFile4Writer.put_variables`

Signature

def put_variables(self, mdict, write_header = None)

Write variables in mdict to stream

mdict : mapping: mapping with method items return name, contents pairs where name which will appeak in the matlab workspace in file load, and contents is something writeable to a matlab file, such as a NumPy array.
write_header : {None, True, False}: If True, then write the matlab file header before writing the variables. If None (the default) then write the file header if we are at position 0 in the stream. By setting False here, and setting the stream position to the end of the file, you can append variables to a matlab file
