Calculate percentage of columns greater than certain value in a matrix using awk
This matrix represents correlation values.
Is it possible to calculate the percentage of columns (a1, a2, a3) that have a value >= |0.5| and report the percentage that has positive correlation >0.5 and negative correlation <-0.5 separately. thanx in advance!

int percent (int a, int b)
{
if (b/a*100 > 25)
return TRUE;
else
return FALSE;
}
I want to calculate what percentage of a is b.
say if b = 48, a = 100
so b is 48% of a
but wouldnt b/a give me 0 ??? what can be done ?? (6 Replies)
i have 3 files like
total.dat=18
equal.dat=14
notequal.dat=16
i need find the equal percentange means:
equalpercentage = ($equal.dat / $total.dat * 100)
How i can do this ?
I tried some of the answers to calculate the percentage in this forums.but it couldn't worked.Some one please... (6 Replies)

mlib_imageautocorrel_fp
mlib_ImageAutoCorrel_Fp(3MLIB) mediaLib Library Functions mlib_ImageAutoCorrel_Fp(3MLIB)NAME
mlib_ImageAutoCorrel_Fp - auto-correlation of an image
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageAutoCorrel_Fp(mlib_d64 *correl,
const mlib_image *img, mlib_s32 dx, mlib_s32 dy);
DESCRIPTION
The mlib_ImageAutoCorrel_Fp() function computes the auto-correlation of a floating-point image, given an offset.
It uses the following equation:
1 w-dx-1 h-dy-1
correl[i] = -------------- * SUM SUM (img[x][y][i] * img[x+dx][y+dy][i])
(w-dx)*(h-dy) x=0 y=0
where w and h are the width and height of the image, respectively.
PARAMETERS
The function takes the following arguments:
correl Pointer to auto-correlation array where size is equal to the number of channels. correl[i] contains the auto-correlation of chan-
nel i.
img Pointer to image.
dx Displacement in the X direction.
dy Displacement in the Y direction.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
