I have a text file of the format
x1 y1
x2 y2

I need to read this into an array. How is this done in Fortran?

I need to read this into an array. How is this done in Fortran?
A 2-d array in Fortran is a data structure that stores data in a grid-like format with rows and columns. It is useful for storing and manipulating large amounts of data.
To create a 2-d array from a text file in Fortran, you can use the READ
statement to read data from the file into an array variable. You will need to specify the correct dimensions for the array and use a DO
loop to read the data into the array.
The syntax for creating a 2-d array in Fortran is REAL, DIMENSION(rows, columns) :: array_name
. This declares a 2-d array with the specified number of rows and columns and assigns it the name array_name
.
Yes, you can create a 2-d array with different data types in Fortran by using the KIND
parameter when declaring the array. This allows you to specify the data type and precision for each element in the array.
Some common errors when creating a 2-d array from a text file in Fortran include not specifying the correct dimensions for the array, not using a DO
loop to read the data into the array, and not properly formatting the data in the text file. It is also important to ensure that the data types in the text file match the data types declared for the array.
