I've assumed that your input file is a plain ascii file that looks like this:

Code:
         AA     AB      AC      BB      ZZ
AA      1       0       0.5     0       0.7
AB      0       1       0.3     0       0
AC      0       0       1       0       0.1
BB      0       0       0       1       0
ZZ      0       0       0       0       1

columns are tab or space separated. If you want to separate them with some other character that'd work, you'll just need to invoke awk with the -F option that supplies the separator character.

then this small awk programme will generate output like you've indicated:
Code:
#!/usr/bin/env ksh

awk '
    NR == 1 {       # read col headers
        for( i = 1; i <= NF; i++ )
            col_lab[i+1] = $(i);
        next;
    }

    {
        for( i = 2; i <= NF; i++ )
            if( $(i)+0 > 0 )
                printf( "%s (gg) %s  = %s\n", $1, col_lab[i], $(i) );
    }
' input-file-name

I replaced the ... with BB just to have a col/row label. The programme will work with any number of rows/columns. Running the sample file above, yields this output:

Code:
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
BB (gg) BB  = 1
ZZ (gg) ZZ  = 1

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
