Hi there,
I want some help on scripting regarding file processing.
I have a scenario in which I have 10 files. (file1.txt, file2.txt....) and they are in paricular format.
I want to read these files and append some text lines at the begining of each file and write this updated contents of... (2 Replies)
Hi All,
Query 1 :
I want to know how we can get a count of multipe occurrences of a particular expression in another string.
For Eg. If my string is " 12" and i need to count the number of spaces preceeding 12

Also want to know how we can change the alignment of a... (9 Replies)
Hi
I have a tab delimited file with 3 fields. I need to sort this file on the first field and remove all the records where the first field has dulplicates. For eg my file is
133|arrfdfdg|sdfdsg
234|asfsdgfs|aasdfs
133|affbfsde|dgfg
When this file gets sorted I need the result to be ... (2 Replies)
Hi ,
I have two files
aaa.txt (which contains)

Dear Gurus,
I need you to advice or suggestion about the best solution to copy data around 200-300G from serverA(location A) to serverB(location B). Normally, I will share folder and then copy but it takes too long time(about 2 days).
Do you have any suggestion or which way should be... (9 Replies)
Hi all,
Is there a way to convert full data matrix to linearised left data matrix?

Hi everyone
I am very new at awk but think that that might be the best strategy for this. I have a matrix very similar to a correlation matrix and in practical terms I need to convert it into a list containing the values from the matrix (one value per line) with the first field of the line (row... (5 Replies)

glmultmatrixd
GLMULTMATRIX(3G)GLMULTMATRIX(3G)NAME
glMultMatrixd, glMultMatrixf - multiply the current matrix with the specified matrix
C SPECIFICATION
void glMultMatrixd( const GLdouble *m )
void glMultMatrixf( const GLfloat *m )
PARAMETERS
m Points to 16 consecutive values that are used as the elements of a 4x4 column-major matrix.
DESCRIPTION
glMultMatrix multiplies the current matrix with the one specified using m, and replaces the current matrix with the product.
The current matrix is determined by the current matrix mode (see glMatrixMode). It is either the projection matrix, modelview matrix, or
the texture matrix.
EXAMPLES
If the current matrix is C, and the coordinates to be transformed are, v=(v[0],v[1],v[2],v[3]). Then the current transformation is Cxv, or
c[0] c[4] c[8] c[12] v[0]
(c[1] c[5] c[9] c[13])x(v[1])
c[2] c[6] c[10] c[14] v[2]
c[3] c[7] c[11] c[15] v[3]
Calling glMultMatrix with an argument of m=m[0],m[1],...,m[15] replaces the current transformation with (CxM)xv, or
c[0] c[4] c[8] c[12] m[0] m[4] m[8] m[12] v[0]
(c[1] c[5] c[9] c[13])x(m[1] m[5] m[9] m[13])x(v[1])
c[2] c[6] c[10] c[14] m[2] m[6] m[10] m[14] v[2]
c[3] c[7] c[11] c[15] m[3] m[7] m[11] m[15] v[3]
Where 'x' denotes matrix multiplication, and v is represented as a 4x1 matrix.
NOTES
While the elements of the matrix may be specified with single or double precision, the GL may store or operate on these values in less than
single precision.
In many computer languages 4x4 arrays are represented in row-major order. The transformations just described represent these matrices in
column-major order. The order of the multiplication is important. For example, if the current transformation is a rotation, and
glMultMatrix is called with a translation matrix, the translation is done directly on the coordinates to be transformed, while the rotation
is done on the results of that translation.
ERRORS
GL_INVALID_OPERATION is generated if glMultMatrix is executed between the execution of glBegin and the corresponding execution of glEnd.
