Re: asciiread

Dear Hong,

You can use sprinti function, like the following line

fileNameString = "MOD_Terra_AODv401_2007"+sprinti("%0.3i",n)
g1 = asciiread( "/usr/rmt_share/scratch79/jam/MODIS_aerosol/2007/" +
fileNameString, -1, "float" )

The code %0.3i in sprinti function create string with 3 numbers and with
leading zeros, like 001 ... 010 ... 099 100 ...
I only split your original line in two to enter in this email.

I hope that it helps you.

Best regards

Mateus
