我先利用fFortran生成了一个名为“u_fla256.dat”的unformatted格式文件 1.在python里面 u=np.fromfile("u_fla256.dat", dtype='d', count=256*256*256) u1=u.reshape(256,256,256) dtype=d, 好像是为了将Fortran双精度的数据转化为python的float数据 2.但是该方法会过分加大系统读取的内存,在节点数很大...
access默认"sequential",表示顺序读写;若设为'direct',则可指定任意位置读写 form'formatted'表示存为文本文件;unformatted表示存为二进制 recl文件字节长度 其中,unit和file为必选参数。 在对文件内容执行完操作后,通过close(unit)来关闭文件。 program fileTest implicit none real, dimension(100) :: x, y inte...

我使用Fortran以以下格式将数据写入二进制文件 open(unit=99,form='unformatted',status='unknown') do i=1,N write(99) (i),(A(i)),(B(i)) enddo close(99) 这里,A 和 B 是双精度数组。如何在python中读取此二进制数据文件? PS:到目前为止,我尝试了以下步骤来读取数据。
I'm having trouble reading an unformatted F77 binary file in Python. I've tried the SciPy.io.FortraFile method and the NumPy.fromfile method, both to no avail. I have also read the file in IDL, which works, so I have a benchmark for what the data should look like. I'm hoping ...
Any ideas what is the right way of writing the data using Python back in the original fortran unformatted format? Details of the problem: I am able to read the final file with manipulated data from Fortran. However, I want to visualize these data using a software (Paraview). For this I...

Fortran的“无格式二进制顺序存取”文件(fortran unformatted sequencial data)。这种文件在不同的操作系统中还细分为big-endian与little-endian版本。而且在存放高位数组集合时,将他们统一的看成很多个二维数组的叠加,然后存放每一个二维数组时会在数组的一头一尾添加特定的占位符,然后再在更高维度重读这种操作,所以直接...
