[ncl-talk] 答复: How to print zero before the decimal point with "write_matrix" function

[Wan Jianghua]

Hi Karin,

Thank you for your reply. I tried several versions of ncl (6.1.2, 6.2.0,
6.3.0). They all got the same results. 

But I run the same script on other two Linux machines with ncl V6.1.2 and
V6.2.0, and  the zero appear.  

I guess the problem might be related to the IBM_AIX machine I was using. 

 

Best,

Jianghua

Hi Jianghua,

which NCL version are you running? Using version 6.6.2 works quite well:

ncl 0> a=new((/2,2/),float,-999.)
ncl 1> a=0.1
ncl 2> a(0,0)=-0.1
ncl 3> write_matrix(a,"2f5.2",True)
  
-0.10 0.10
 0.10 0.10
  
ncl 4> quit

Hi all,

I try to print a nicely formatted text file with “write_matrix” function,
but the result is not satisfactory.

When the absolute value of the number is less than 1, the zero before the
decimal point is omitted. Is there any possible way to print it out? Thanks!

 

My test script:

a=new((/2,2/),float,-999.)

a=0.1

a(0,0)=-0.1

write_matrix(a,"2f5.2",True)

 

the result:

-.10   .10

.10   .10



 

Sincerely,

Jianghua
