Information for Jitter Matrix Operator (MOP) messages and attributes to this object

Messages

read filename [symbol]
Open and read a single matrix from a text file. The optional argument specifies the filename. The jit.fprint object expects text files to be formatted in the same fashion in which it writes them. Attempting to read unformatted text files will likely return an error.
write filename [symbol]
Create a new text file for writing. The optional argument specifies a filename. The text file is not written until a matrix is received by the jit.fprint object. After a write attempt, the message write followed by two int arguments will be sent from the object's right outlet. The first int indicates the success (1) or failure (0) of the write operation, and the second int indicates the number of bytes written to the file (if any).
