read4b - fortran file binary read
- x=read4b(file-name,m,n [,rec])
: string or integer
- m, n
: integers (dimensions of the matrix x). Set m=-1 if you do not know the numbers of rows, so all the file is read
: vector of positive integers. the selected records for direct access. This vector size must be equal to the number of rows of desired x.
binary read of the matrix x in the file file-name.
Matrix entries are supposed to have been stored on 4 byte words.
For direct record access, file must have been previously opened using
file function to set the record_length. file-name must be
the result of the file function.
