awk? adjacency matrix to adjacency list / correlation matrix to list
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 annotation) && the header of the field (column annotation) and some spaces etc. preceding it.
In more abstract terms, I wish to convert an adjacency matrix into adjacency list, which includes the edge weights. In excel it works fine with =IF(B2>0;$A2&" (gg) "&B$1&" = "&B2;"") and some grep but the datasets became just to big. P.S 0 values should be omitted.
Input
 AAABAC...ZZ
AA100.500.7
AB010.300
AC00100.1
...00010
ZZ00001

Output
AA (gg) AA = 1
AA (gg) AC = 0.5
AA (gg) ZZ = 0.7
AB (gg) AB = 1
AB (gg) AC = 0.3
AC (gg) AC = 1
AC (gg) ZZ = 0.1
... (gg) ... = 1
ZZ (gg) ZZ = 1


Thanks a million for your efforts☺.

glmatrixmode

GLMATRIXMODE(3G)														  GLMATRIXMODE(3G)

NAME

       glMatrixMode - specify which matrix is the current matrix

C SPECIFICATION

       void glMatrixMode( GLenum mode )

PARAMETERS

       mode  Specifies which matrix stack is the target for subsequent matrix operations.  Three values are accepted: GL_MODELVIEW, GL_PROJECTION,
	     and GL_TEXTURE.  The initial value is GL_MODELVIEW.

	     Additionally, if the GL_ARB_imaging extension is supported, GL_COLOR is also accepted.

DESCRIPTION

       glMatrixMode sets the current matrix mode.  mode can assume one of four values:

       GL_MODELVIEW		Applies subsequent matrix operations to the modelview matrix stack.

       GL_PROJECTION		Applies subsequent matrix operations to the projection matrix stack.

       GL_TEXTURE		Applies subsequent matrix operations to the texture matrix stack.

       GL_COLOR 		Applies subsequent matrix operations to the color matrix stack.

       To find out which matrix stack is currently the target of all matrix operations, call glGet with argument GL_MATRIX_MODE. The initial value
       is GL_MODELVIEW.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_OPERATION is generated if glMatrixMode is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_MATRIX_MODE
