2D Array to display characters
Hi All,
I have a series of number which indicates the coordinates where 0104 indicates X-coord = 01 and Y-coord = 04 and i want characters to form up in accordance to the coordinates given. Can any expert give me an example of 2D array code using csh or awk or perl such that the code can display the characters below ? EG: Inputfile: 0101 A 0102 B 0103 C 0104 D 0201 E 0202 F 0203 G 0204 H 0301 I 0302 J 0303 K 0304 L Code:
04 D H L 03 C G K 02 B F J 01 A E I 01 02 03 Last edited by Raynon; 02-27-2008 at 03:26 AM.

This way:
Code:
awk '{
X[$2]=substr($1,1,2)
Y[$2]=substr($1,3)
}
END {
for ( y in Y)
for ( x in X )
if ( x == y )
{
dx=sprintf("%d",X[x])
dy=sprintf("%d",Y[y])
if ( dx >= max_x )
max_x=dx
if ( dy >= max_y )
max_y=dy
f[dx,dy]=x
}
for (i=max_y;i>=1;i--)
{
printf("%2d",i)
for (j=1;j<=max_x;j++)
printf(" %2s",f[j,i])
printf("\n")
}
printf(" ")
for (j=1;j<=max_x;j++)
printf("%2d ",j)
print
} ' file
4 D H L
3 C G K
2 B F J
1 A E I
1 2 3

Hi Klashxx,
Your code is really cool. Thks , it works up till a 9x9 matrix. However, I tried the code with x-coordinates 10 and above and it doesn't work. Can you help ? EG: Inputfile: 0101 A 0102 B 0103 C 0104 D 0201 E 0202 F 0203 G 0204 H 0301 I 0302 J 0303 K 0304 L 1001 M 1002 N

Ok, it was a conversion problem, so:
Code:
> cat file 0101 A 0102 B 0103 C 0104 D 0201 E 0202 F 0203 G 0204 H 0301 I 0302 J 0303 K 0302 L 0903 U 1001 M 1002 N 1104 Ñ 1504 F 2005 N Code:
>awk '{
X[$2]=substr($1,1,2)
Y[$2]=substr($1,3)
}
END {
for ( y in Y)
for ( x in X )
if ( x == y )
{
dx=X[x]+0
dy=Y[y]+0
if ( dx >= max_x )
max_x=dx
if ( dy >= max_y )
max_y=dy
f[dx,dy]=x
}
for (i=max_y;i>=1;i--)
{
printf("%.2d",i)
for (j=1;j<=max_x;j++)
printf(" %2s",f[j,i])
printf("\n")
}
printf(" ")
for (j=1;j<=max_x;j++)
printf("%.2d ",j)
print
} ' file
05 N
04 D H Ñ F
03 C G K U
02 B L
01 A E I M
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20

Hi Klashxx,
Strange, i tried to use yr modified code but some strange characters appear at the end of output in blue. Can you give some advice on that Code:
$ cat input1 0101 A 0102 B 0103 C 0104 D 0201 E 0202 F 0203 G 0204 H 0301 I 0302 J 0303 K 0302 L 0801 Z 0903 U 1001 M 1002 N $ awk -f 2d_array input1 04 D H 03 C G K U 02 B F L N 01 A E I Z M 01 02 03 04 05 06 07 08 09 10 1002 N

Hi Klashxx,
Thks a million!!!!. It works!! Thats real cool!!. But i am a beginner in awk, can you explain your code such that i can comprehend better. Especially the looping part, which seems confusing to me.
