Re: Reading files is slow

[Tom Kornack]

Notes:

1. Indeed, I should clarify that I'm reading a text, tab-delimited 
file. Is there an easy way (is there a common tool) to convert this 
file into a binary file?

2. load seems to be finicky about carriage returns and line feeds. I 
work in an extremely heterogeneous computing environment. What is 
octave's requirement and is there a convenient tool to convert text 
files to have the appropriate line ending sequence?

3. Please excuse my skull thickness, but can you clarify this process 
of putting text data into a buffer by treating it as binary? I'm afraid 
I need some examples. And why wouldn't this be implemented in a decent 
text-data reading algorithm?

4. I can't find the procedure wavread. Is this shorthand or a procedure?
