Shell Script not working using for loop and a funtion
Hi-
Here is the shell script that for some reason is not returning results:
If you run it would simply say "Average of numbers (list the numbers) is"
and give me this error
Thanks

i have this code for a simple if loop:

array="1 2 3 4 5"
array2="5 6 7 8 9"
if } -gt ${array} ]; then
echo "${array2} is greater than ${array}!!"

the error is

It is happening with my sessions already second time: a 'for'-loop for some reason stop to work as expected.
That means or it is looping without exitting, or it is not loop even once.
Here example of my try when it is not processing even one loop.

Trying to figure out why this works:

$A = `pwd`;
print "$A\n";

Hi, I am new here I have used the forums a long time to search for things they are very helpful. I have unfortunately used up all my resources (professors, grad students) and need some help.

i wrote a shell program in Home Directory.
and i changed to other directory.
i want to try to execute shell script in Other Dir.
it is not executed.
how can i make this script to execute in other directory also??
Thanks,

mlib_imagenormcrosscorrel_fp
mlib_ImageNormCrossCorrel_Fp(3MLIB)mlib_ImageNormCrossCorrel_Fp(3MLIB)NAME
mlib_ImageNormCrossCorrel_Fp - normalized cross correlation
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageNormCrossCorrel_Fp(mlib_d64 *correl, const mlib_image *img1, const mlib_image *img2, const mlib_d64 *mean2, const
mlib_d64 *sdev2);
The mlib_ImageNormCrossCorrel_Fp() function computes the normalized cross-correlation coefficients between a pair of floating-point images,
on a per-channel basis.
It uses the following equations:
w-1 h-1
SUM SUM (d1[x][y][i] * d2[x][y][i])
x=0 y=0
correl[i] = -------------------------------------
s1[i] * s2[i]
d1[x][y][i] = img1[x][y][i] - m1[i]
d2[x][y][i] = img2[x][y][i] - m2[i]
1 w-1 h-1
m1[i] = ----- * SUM SUM img1[x][y][i]
w*h x=0 y=0
1 w-1 h-1
m2[i] = ----- * SUM SUM img2[x][y][i]
w*h x=0 y=0
w-1 h-1
s1[i] = sqrt{ SUM SUM (img1[x][y][i] - m1[i])**2 }
x=0 y=0
w-1 h-1
s2[i] = sqrt{ SUM SUM (img2[x][y][i] - m2[i])**2 }
x=0 y=0
where w and h are the width and height of the images, respectively; m1 and m2 are the mean arrays of the first and second images, respec-
tively; s1 and s2 are the un-normalized standard deviation arrays of the first and second images, respectively.
In usual cases, the normalized cross-correlation coefficient is in the range of [-1.0, 1.0]. In the case of (s1[i] == 0) or (s2[i] == 0),
where a constant image channel is involved, the normalized cross-correlation coefficient is defined as follows:
#define signof(x) ((x > 0) ? 1 : ((x < 0) ? -1 : 0))
if ((s1[i] == 0.) || (s2[i] == 0.)) {
if ((s1[i] == 0.) && (s2[i] == 0.)) {
if (signof(m1[i]) == signof(m2[i]) {
correl[i] = 1.0;
} else {
correl[i] = -1.0;
}
} else {
correl[i] = -1.0;
}
}
The two images must have the same type, the same size, and the same number of channels. They can have 1, 2, 3 or 4 channels. They can be
of type MLIB_FLOAT or MLIB_DOUBLE.
If (mean2 == NULL) or (sdev2 == NULL), then m2 and s2 are calculated in this function according to the formulas shown above. Otherwise,
they are calculated as follows:
m2[i] = mean2[i];
s2[i] = sdev2[i] * sqrt(w*h);
where mean2 and sdev2 can be the output of mlib_ImageMean() and mlib_ImageStdDev(), respectively.
In some cases, the resulting coefficients of this function could be NaN, Inf, or -Inf.
The function takes the following arguments:
correl Pointer to normalized cross correlation array on a channel basis. The array must be the size of channels in the images.
correl[i] contains the cross-correlation of channel i.
img1 Pointer to first image.
img2 Pointer to second image.
mean2 Pointer to the mean array of the second image.
sdev2 Pointer to the standard deviation array of the second image.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
