Hello
I would like to know where there is a difference between these two machines?
HP9000-735/125
HP9000-B132L
What does that all mean?
Okay, HP= Hewlett Packard
But 9000, 725/125, B132L ????
I am asking that question because I am about to buy one for myself, so I can have some fun... (3 Replies)
just wondering what the difference is between 1,$ and /g when doing a substitution in vi. doesn't seem to be much difference from what i can see. (2 Replies)

Hi ..
I am trying to create one function.
It will have two arguments.
Argument1: a,b,d,f,g
Argument2:21212,sfsd,4546,67867,a,asda,b
So the output will be Argument1 - Argument2
which is d,f,g
Can anyone help with this one? (4 Replies)
In the awk I am trying to subtract the difference $3-$2 of each matching $4 before the first _ (underscore) and print that value in $13.
I think the awk will do that, but added comments. What I am not sure off is how to add a line or lines that will add sum each matching $13 value and put it in... (2 Replies)

pgmtexture(1) General Commands Manual pgmtexture(1)NAME
pgmtexture - calculate textural features on a portable graymap
SYNOPSIS
pgmtexture [-d d] [pgmfile]
DESCRIPTION
Reads a portable graymap as input. Calculates textural features based on spatial dependence matrices at 0, 45, 90, and 135 degrees for a
distance d (default = 1). Textural features include:
(1) Angular Second Moment,
(2) Contrast,
(3) Correlation,
(4) Variance,
(5) Inverse Difference Moment,
(6) Sum Average,
(7) Sum Variance,
(8) Sum Entropy,
(9) Entropy,
(10) Difference Variance,
(11) Difference Entropy,
(12, 13) Information Measures of Correlation, and
(14) Maximal Correlation Coefficient.
Algorithm taken from:
Haralick, R.M., K. Shanmugam, and I. Dinstein. 1973. Textural features for image classification. IEEE Transactions on Systems, Man, and
Cybertinetics, SMC-3(6):610-621.
BUGS
The program can run incredibly slow for large images (larger than 64 x 64) and command line options are limited. The method for finding
(14) the maximal correlation coefficient, which requires finding the second largest eigenvalue of a matrix Q, does not always converge.
