FORTRAN90阵列读取空白值作为空 [英] Fortran90 Array read blank values as null
问题描述
我读数据FRAM一个外部文本文件（30行，第7列），每个行被分隔以一，。我已经缺失值重新psented为$ P $,,。当我读数据到一个二维数组的缺失值被替换为0.00，但我已经在数据中的0.00太超值了。当我计算平均计数（件数（n））showd是计数 - （缺失值的数目）。如何动态挑缺失值。
谢谢

您似乎没有在你的数据负值，如何将数据传递到FORTRAN，在那里你替换之前做一些pre-处理',,'具有一个负值，例如用
SED的/ ,, /， - 1 / G'
然后你就可以很容易地在Fortran程序识别这些无效的数据，并相应地对待它。
I'm reading data fram a external text file (30 Rows, 7 Columns), each row is seperated with a ",". I have missing values represented as ",,". When i read data into a two dimensional array the missing value is replaced with 0.00, but i have a 0.00 value in the data too. When i am computing average the count (number of items (n)) showd be count - (number of missing values). How can i pick the missing values dynamically.
Thanks Sri

You do not seem to have negative values in your data, how about doing some pre-processing before passing the data to fortran, where you replace the ',,' with a negative value, for example with
sed 's/,,/,-1,/g'
Then you can easily identify these invalid data in your Fortran program and treat it accordingly.
