Hello,
 
I was wondering ... what is the best way to scan a 2d array of numbers from a text file.
An example of such a text file:
 
  0.0000000e+000  3.5000000e+001  3.5100000e+001  3.5200000e+001  3.5300000e+001  3.5400000e+001  3.4000000e+002 -5.4998976e+000 -1.4999700e+000  0.0000000e+000 -1.4999700e+000  2.9999400e+000  3.4066602e+002 -5.5554708e-002 -5.5554708e-002  1.1110942e-001 -4.4444529e-001  1.6666667e-001  3.4133203e+002 -1.2499914e+000  2.2499949e+000  7.5000244e-001 -2.2499826e+000  1.7500051e+000  3.4199805e+002  6.8420986e-001  1.2105260e+000  1.1578951e+000  1.1578951e+000  1.2631568e+000  3.4266406e+002  7.1428082e-001  1.5714212e+000  1.9999914e+000  5.7142626e-001  5.7141972e-001  3.4333008e+002  2.6667133e+000  3.3333832e+000 -1.1753165e-005 -3.3334667e-001 -1.1753165e-005

Hi John,
use the "read from text file.vi" and then the "spreadsheet string to array function". Before that replace all "\s\s" to "\s" code display. After that you will have your 2d array of double values.

Read From Spreadsheet will work as long as you specify the correct delimitor.

Mike, I did not know you could feed an array of delimiters to the Spreadsheet String to Array function. I could have used that yesterday. Thanks for showing that.Lynn
