hello everyone,
here is the problem. I need to read numeric values from an ASC file which doesn't have any predefined format. The only thing I know is the number of values I'm supposed to read. FORTRAN will read it as:
READ(12,*) (NV(J),J=1,NUMBER)
(the ASC file is like that because it is used by an old FORTRAN code)
The values can be in a multi-line string or not (example below). READF will read one number per line only. Read the whole line as a string and use STRSPLIT doesn't work because the whole data set might be multi-line. The number of values per line may also change (the format also).
Messy I know. Any tip or tricks?
many thx
Paula
For example, I need to read 197 than 33 numbers from a file like below:
0.00 2042.39 4058.52 6048.34 8011.79 9948.83 0.00 2042.39 4058.52 6048.34
8011.79 9948.83 11859.39 0.00 2042.39 4058.52 6048.34 8011.79 9948.83 11859.39
13743.42 0.00 2042.39 4058.52 6048.34 8011.79 9948.83 11859.39 13743.42 15600.88
