Fortran Printing 1D array in Fortran as 2D array

Click For Summary
The discussion centers on printing all row entries from a two-dimensional array in Fortran. A code snippet demonstrates how to use a DO loop to write each row of the array to an output. The conversation highlights the use of the colon (:) as an implicit "all" operator for arrays and clarifies the difference between a colon and a semicolon. There is also a mention of confusion between Fortran and ANSYS APDL syntax. Additionally, a participant advises against deleting posts, emphasizing the importance of shared knowledge for others who may benefit from the discussion.

They're not crazy, if I want to print all row entries in a column, then:
Code:
REAL,DIMENSION(2,3) :: array

DO,i=1,2
  WRITE(6,*) array(i,:)
END DO

You can use the semi-colon as an implicit "all" when operating on arrays.
 
Yes. In C, two-dimensional arrays are simply one-dimensional arrayswhose element type is itself a one dimensional array. Since one-dimensional arrays are required to occupy contiguous storage, itfollows that the same must be true for an array of arrays.

I don't think you want that first comma after the DO.

This character - : - is a colon. This one - ; - is a semicolon.
 
Right-o, as far as the comma, I occasionally get f90 and ANSYS APDL mixed up a bit. Also can't believe I called a, ':', a semi-colon. 1:11pm, perhaps, I was in a lunch daze.

BC2210,
Although it's possible for you to delete your own post, it's not a good idea to do so. Other people can possibly learn from your question.
 
but why you want to delete the post was it not relevant
 
may be it was
