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

[Karin Meier-Fleischer]

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
